Overview
“BGM” is an album by the Japanese electronic music band Yellow Magic Orchestra (hereafter YMO), their fifth overall, or their fourth if the mini-album “×∞Multiplies” is excluded. It was released by Alfa Records on March 21, 1981. The title is an abbreviation of “background music,” yet the work is experimental in character, marked by the increasing complexity of rhythm, the transformation of timbre into noise, and the obscuring of both melody and harmony.

The album peaked at No. 2 on the Oricon chart, sold approximately 275,000 copies in total, and ranked 28th among the year’s best-selling albums in 1981.
In November 1981, another experimental album “Technodelic” was released, and the two albums of that year represent the peak of YMO’s middle period.
Background
Following their debut in 1978, YMO achieved commercial success with catchy synth-pop built on a foundation of disco beats, as typified by “Rydeen.” With “BGM,” produced after “×∞Multiplies” (1980), the band turned toward a more introspective and intelligent music. The members themselves described this shift as a “culling of fans,” and it indicates that the pursuit of their own musical interests took precedence over commercial success. It has also been said that weariness with repeatedly performing the same songs in concert fueled their interest in more complex compositions.
The album drew its principal inspiration from two records released in 1980: Ryuichi Sakamoto’s solo album “B-2 Unit” and Kazuhiko Katō’s solo album “L’Opéra Fragile.”
“B-2 Unit” is an experimental album that fully embraces dub techniques, and it exerted a direct influence on “BGM.” Haruomi Hosono is said to have admired its track “Riot in Lagos,” which sustains a loop on a single chord, and he chose it as the opening number of YMO’s second World Tour in the autumn of 1980.
Katō’s “L’Opéra Fragile,” on which Haruomi Hosono and Yukihiro Takahashi participated, is an album themed on 1920s Berlin, and its European romanticism also influenced this album.
Recording took place at Studio “A” from January 15 to February 20, 1981, on a schedule designed to meet the March 21 release date. The lyrics were not ready in time for printing and were first made public in the photobook “OMIYAGE.”
Production Methods
The album was made with deliberately modest equipment: the Prophet-5 as the synthesizer and the TR-808 as the rhythm machine. These were played through amplifiers in the studio, picked up by microphones, recorded on a TEAC eight-channel recorder, and then dubbed onto 3M’s digital multitrack recorder, the DMS. Passing the signal through the analog domain in this way reflects an approach in which sounds were processed with equipment in the studio rather than constructed within the synthesizer itself, and it is regarded as an early example of what later came to be called “tape compression.” Sakamoto, however, said in a later interview that he was not enthusiastic about the method, which he felt resembled imitating the bedroom recording practices of Britain at the time.
The sequencer was changed from the MC-8 to the MC-4. Other instruments used included the Minimoog, the ARP Odyssey, and the Roland Jupiter-8. Acoustic instruments were hardly used. However, Sakamoto plays piano on some tracks, such as “U·T.”
The drums make extensive use of gated reverb, a cutting-edge acoustic effect of the period that became widely known through XTC’s album “Black Sea” (1980).
Takahashi’s drums feature a noisy timbre produced by a noise oscillator, custom-ordered from Ishibashi Gakki and attached to the rim of the snare drum.
The dry texture of the TR-808 and the effect-driven handling of space characterize the impression of the album as a whole.
Eight of the ten tracks run about four and a half minutes, and the remaining two about five minutes and twenty seconds, so the running times are nearly uniform.
The lyrics were written by the members themselves, with Peter Barakan responsible for the English translation and pronunciation coaching.
Reception
On its release, “BGM” was regarded as difficult by general listeners who had expected the pop and catchy image of the band’s earlier work, and its sales did not match those of “Solid State Survivor.” In later reassessments, however, it has been highly praised as one of the albums in which YMO’s experimentalism was most fully realized, and it is often positioned as a precursor of ambient techno and minimal techno.
In a review published in March 2021 by the American music outlet Pitchfork, the musician and music writer Noah Yoo described the album as a technically accomplished and enormously expensive production whose shadow still falls over four decades of electronic music-making. He wrote that it offered a “startlingly prescient” glimpse of where electronic music was heading, and he pointed to the groove of “Rap Phenomena,” the ambient approach of “Happy End,” and the drum programming of “U·T” and “Camouflage” as influences on later IDM, ambient techno, and hip-hop.
The members themselves also hold the album in high regard. Haruomi Hosono has cited it as one of YMO’s best works for its timeless sound and the quality of its lyrics, while Yukihiro Takahashi has likewise ranked it among their finest, praising it as the first album in which they fully expressed what they had long wanted to say through lyrics, with words and sound coming together seamlessly.
In Japan, critic Eiichi Yoshimura, in his book “Compact YMO” (1998) and elsewhere, noted that the album was harshly criticized at the time of release as “dark” and “drab,” yet positioned it as essential, stating that “YMO’s dedicated fanbase cannot be understood without this album and the subsequent Technodelic.” He praised it as “a masterpiece that will never fade, no matter how much the times or musical trends change.” CD Journal similarly described it as “the darkest and highest-quality album in YMO’s history” and “a work that should be listened to for eternity as the world’s first ambient techno.”
Outside of Pitchfork, notable international reviews include a contemporary assessment in Stereo Review (1981), which praised the “crystalline” clarity of the recording, the “remarkable” fusion of East and West, and the ambitious use of electronics, while also noting that these qualities made the album less immediately accessible to general listeners. Music writer Malachi Lui, writing for the American web media outlet Analog Planet in August 2021, highly praised it as “the group’s most experimental, forward-thinking work” (Music: 9/10, Sound: 9/10), highlighting the IDM-like soundscape of “Ballet” and the electronic textures of “Loom” that anticipated Aphex Twin’s “Selected Ambient Works 85–92” (1992). AllMusic’s Ted Mills offered a mixed assessment, praising tracks such as “Cue,” “U·T,” and “Loom” while criticizing some of the material on the first half of the album.
Overall, while the album received some harsh criticism at the time of its release due to the gap between commercial expectations and its experimental direction, its technical innovation and musical experimentation have been highly reappraised in later years, and it is now recognized both in Japan and abroad as an important turning point in the history of electronic music.
Song Commentary
1. “Ballet” (lyrics: Yukihiro Takahashi, Peter Barakan; music: Yukihiro Takahashi)
A piece that holds both sweetness and romanticism within a dark atmosphere. The lyrics take as their subject the Art Deco painter Tamara de Lempicka, with Takahashi evoking the atmosphere of Warsaw in fog. Hosono created the sound-effect-like timbres with a locomotive in mind. The French voice is that of Tomoko Nunoi.
2. “Music Plans” (lyrics: Ryuichi Sakamoto, Peter Barakan; music: Ryuichi Sakamoto)
This is the only newly written piece Sakamoto contributed to the album, and he also sings the vocals. The lyrics are infused with irony and defiance toward music-making. A single “pop” can be heard at one point in the track, which stems from jitter noise caused by a data error on the digital recorder.
3. “Rap Phenomena” (lyrics: Haruomi Hosono, Peter Barakan; music: Haruomi Hosono)
The title plays on two meanings of “rap,” the rapping of spirits in paranormal phenomena and the rap of hip-hop, which was just beginning to attract attention at the time. Hosono keeps speaking about “rap phenomena” in a rap-like manner throughout the piece. Hip-hop was not yet widely known then, and the track is regarded as one of the earliest rap songs by a Japanese artist.
4. “Happy End” (music: Ryuichi Sakamoto)
This is a dub-style reconstruction of the B-side of Sakamoto’s solo single “Front Line” (1981), with an ambient quality. Because the main melody has been removed, it sounds like a different piece from the original. At the 1981 Winter Live, it was performed in an arrangement close to the original. A piano quartet version appears on Sakamoto’s 2005 album “/05.”
5. “1000 Knives” (music: Ryuichi Sakamoto)
This is a re-recording (self-cover) of a track from Sakamoto’s 1978 solo album “Thousand Knives.” Although it was frequently performed at YMO concerts, the arrangement on this album is more experimental. In the middle section, a synthesizer solo that makes full use of pitch bend unfolds in an aggressive timbre reminiscent of a distorted guitar. Sakamoto has said that he drew on Talking Heads’ album “Remain in Light” (1980), on which Adrian Belew participated, for this solo.
6. “Cue” (lyrics: Yukihiro Takahashi, Haruomi Hosono, Peter Barakan; music: Yukihiro Takahashi, Haruomi Hosono)
Later released as a single, this is one of the album’s representative songs. The influence of the contemporaneous band Ultravox is evident, especially that of “Passionate Reply,” the B-side of their 1981 single “Vienna,” and similarities in the rhythm parts and timbres have been pointed out. Sakamoto is said to have felt the song was an imitation of Ultravox and to have stayed out of the recording. With its catchy melody and Takahashi’s vocals, it is one of the more pop-oriented tracks on the album.
7. “U·T” (music: YMO)
The title is an abbreviation of “Ultra-Terrestrial.” This instrumental is characterized by rapid-fire sixteenth-note drums, a “clattering” pattern that makes heavy use of digital delay and gated reverb. An ambient melody is layered over a minimal drum loop. In the middle section, the members speak about “U·T” in processed voices. The track was also performed live and is regarded as one of the highlights of the album. It was also included as the B-side of the single “Cue.”
8. “Camouflage” (lyrics: Yukihiro Takahashi, Peter Barakan; music: Yukihiro Takahashi)
A dark and tense piece composed by Takahashi, it uses microtones (in particular 31-tone equal temperament) to produce an unstable and alien sound that cannot be obtained in the usual 12-tone equal temperament. In the latter half, Takahashi’s heavily effects-processed voice appears. This track was also included as the B-side of the single “Mass.”
9. “Mass” (lyrics: Haruomi Hosono, Peter Barakan; music: Haruomi Hosono)
This song was later released as a single. The title carries a double meaning, referring both to the masses and to the Mass (a religious rite). The piece evokes the atmosphere of a solemn ritual, and the spirituality and mystical elements characteristic of Hosono are strongly felt. Peter Barakan recites the lyrics in two languages, English and Russian.
10. “Loom” (music: YMO, Hideki Matsutake)
This ambient piece foregrounds an endlessly rising scale (an auditory illusion close to the Shepard tone). Ascending and descending tones sound simultaneously, and the piece is constructed so that it seems to rise without end (created by Hideki Matsutake using an E-mu). It is an experimental closing track, and it also gives an impression of anticipating THX’s “Deep Note” (the electronic sound effect heard with the THX logo in cinemas, in which a dense cluster of low tones gradually spreads out to form a chord).
