In 1976 Michael Hoenig had a brief collaboration with Manuel Göttsching of Ash Ra Tempel; a 48 minute recording of one of the sessions was released in 1995 under the title Early Water.
Michael Hoenig talks about the release of Early Water in an interview with Christopher Lawless and Michael Darnell: "I recently had a prolonged flashback to those days when somebody discovered some tapes that I didn't even know existed. While I had been working on Departure From The Northern Wasteland, Manuel Göttsching from Ash Ra Tempel had asked me if I would team up with him for some concerts in France, since his group had just gone through one of its hibernation periods. We rehearsed in my place for three or four weeks. One evening we got a call regarding some missing guarantee, which ultimately led to the decision to cancel the tour. Just for fun, we played one of the planned sets for a last time. Even though I do not recall pressing a record button, somebody recently dug up a Revox tape of that very set. After performing some digital sonic archaeology on it, it was just released under the very appropriate title Early Water. [...] I honestly don't know who found the tape, or where it came from. It might have been Lutz Ulbrich, who used to play with Agitation Free and who still works with Manuel sometimes. He might have found it in my old basement in Berlin while trying to find some forgotten tapes of Agitation Free. I was totally unaware of its existence until Bernd Kistenmacher, who runs a small label in Berlin, sent me a cassette asking if I recognized the material. He sent the same tape to Manuel, who remembered immediately. It was actually delightful and somewhat amusing to work again on something that appears almost ancient now. I had totally forgotten the entire episode -- so many other good things had happened for me at the time."
