I got this from rutracker torrent site and somebody (possibly original uploader - thank you mishka1981) was carrying enough to make complete early ECM-like CD artwork for it. I found it while searching for Eberhard Weber and realized later that this is his first ECM date ever. Probably one of the weirdest albums on the label, it was well described by Tyran Grillo on his "between sound and space" blog:
An early outlier in the ECM catalog, Output convulses with as much lively originality as it did when it was first released. Wolfgang Dauner, perhaps better known as founder of the United Jazz + Rock Ensemble, assembles a modest trio of talent for this classic 1970 studio free-for-all. The end result is humor, provocation, brilliance, and chaos all rolled into one. (...) Superb, if jumbled, musicianship and a strong attention to detail make for a unique experience all around. Dauner does wonders with limited means, Braceful sheds his skin at every turn, and this is a far cry from the Weber of the languid orchestral suites. Not an easy listen for the faint of heart, but one that will give back what’s put into it. Viable candidate for quirkiest album cover of all time?
