Their sole album does open with its most experimental material: Do Your Own Thing starts with an audio-verite recording from Hamburg's central railway station, which gives way to a great atmospheric echo-guitar piece. After this, the instrumentation gradually expands, with Others Do a nice funky guitar-bass-drums jam that adds organ at the end to continue into the third track Already.
The sound quality is a bit muffled, especially on those two tracks - Hyperthalamus is apparently comprised of live recordings stitched together at a time when the band was to all intents and purposes finished. Despite the lower fidelity, it's clear that this band had decent fusion chops, and the 19-minute album closer Grey Present Tense gives all the band members room to stretch out, including flute and sax solos and a short synth passage. Bohn and Wili Pape, as trailered on the Hyperthalamus LP sleeve, next ended up in Kickbit Information with Uli Trepte; they didn't even get as far as releasing an album, but a rehearsal tape did emerge 20 years later. I don't have that, but for now enjoy this one-off from Dennis.
