2 Classic and still fairly unknown German underground Lp's by Deuter. Fans of early Faust, Ashra Temple, Drone Raga, and psychedelic outsider tones will dig this record. I am not just saying this like the millions of albums these days that get touted and don't live up to it. Deuter went on to release probably over 30 records and pretty much found the New Age Ambient scene, though he does not consider himself New Age... One of those dumb terms I guess.
'D', his first Lp has some amazing organ drones and the second track on the album "Der Turm/Fluchpunkt" sounds like faust running a Indian Slide through some Wümme fuzz with some killer percussion in the background. Other tracks delve into some dark Organ Drones with field recordings blended in. Which he takes even further with the following album 'Aum'
'Aum' is a good send off album still with lingering psychedelic moments and lots of strange processing, REVERBBBBB, Sitars, the Ocean, voices, & bongo's... Truly a well rounded and deep album. Heads take note!
From this point you can move forward into the Third Eye of Deuter. A few of the mid 70's records by him and some really nice bits, but by the 1980's its pretty much ambient meditation music. He now lives in New Mexico and still makes music in his home studio for various therapy and relaxation.
