The original duo during the year had grown to four and occasionally hosting other musicians played in the same form until 2008. The group mixed ambient, urban ethno, dub, post rock, trip hop and punk jazz. B4 since 2008, is a kind of power trio, playing a wild mixture of krautrock, noise and psychedelic. All heavily wrapped in space effects and electronic roaring, adding some odd rhythms and disharmonies. The music can range from meditative minimalism to noise soudwalls. The group is drums, analog keyboards, bass and mixing pult. Sometimes B4 plays with guest bassist, and then the setup is completed by coughing and sizzling electric guitar.
