“Leucocyte” is the twelfth album by e.s.t. (Esbjörn Svensson Trio), a Swedish jazz piano trio formed in Stockholm in 1993 by Esbjörn Svensson (piano), Dan Berglund (double bass), and Magnus Öström (drums).
It was recorded in 2007, and released by ACT Music in 2008.
It is contemporary jazz in the style of electroacoustic music, centering around Esbjörn Svensson’s aesthetic piano like Keith Jarrett or the artists of the ECM records, and making heavy use of electronic sounds, electronic effects, and noises.
The album was produced by the trio’s improvisation in an Australian studio and the post-production. It mainly consists of two long tracks in the suite form.
Though it includes jazzy pianism and improvisation, it is closer to post-rock and alternative rock, such as Sigur Rós and Radiohead, and ambient/glitch techno such as Fennesz than traditional jazz as a whole.
The two albums produced from the 2007 session, “Leucocyte” (2008) and “301” (2012) became the trio’s last albums because Svensson died in a scuba diving accident in 2008.
