Inter-Media-Art, with drummer Sepp'l Niemeyer (since 2007)

Jakob has been Sepp'ls successor in the role of musical director for antagon theaterAKtion, which significantly shaped their musical collaborations, as well as their friendship.

Both share a love for the theatrical, and so their music, a mix of psychedelic melodies, electronic beats, poetic vocals and hard riffs, comes to life on stage with the manipulating force of a machine-armada, integrated in a visual interactive concept.

Due to a lack in opportunity to synchronize their time schedules, KieselStein remains an "exceptional" project, in both appearance and essence, only taking place when circumstances allow for it to happen. Preproduction on a studio recording has commenced.
