In 2004 UK trombonist Hilary Jeffery and Swiss cellist Nina Hitz joined TKDE to record the self-titled debut album which was released on Planet Mu Records in May 2006. The ensuing tour saw Eelco Bosman and Paris based vocalist Charlotte Cegarra join, forming the Ensemble into a sextet. London based violinist Sadie Anderson joined in 2008 to supply the group with extra power on stage.
The Netherlands has been TKDE’s homebase since 2007, while members have moved closer to each other to make composing and producing easier.

Apart from the mothership which is TKDE, there is another entity; The Mount Fuji Doomjazz Corporation is a live improv jazz/drone/doom sideproject consisting of TKDE members and a host of interchanging guest musicians.

Due to the vast possibilities within the band, the sound spectrum of TKDE is hard to capture within one specific composition. Moreover, the project will lean towards various styles depending on the respective members working together at a given time. A good mix between atmosphere and technique is always the strong basis for a TKDE composition.

Live TKDE fuse analog and digital as much as possible. Combining traditional instrumentations (comprising cello, trombone, violin, beats, guitar, bass and vocals) with existing and/or self-developed software, continuously blending and mutating, creating an organic and electronic performance, supported by visuals which add to and interact with the frequencies of said instruments.
