It all started at the "Weisser Wind" of Zürich, in April 1971. Seven Swiss, three Danes, an American and a Swede, played the whole evening of the 27th, experimenting new sounds and melodies, for all the free jazz lovers... The result is just astonishing, brilliant and out of time !!! That session will always remain timeless, as these sounds (more than music) transports you elsewhere, allowing a long interior mediation. Of course, you can call it free and experimental jazz / rock but I don't think it can properly be classified. This so dense album is properly a chronological history of music: hear it a hundred times, you'll always discover new things in it ! After a few plays, it's to me a subtle and refined melange of Stravinski, Miles Davis (especially Bitches Brew) and Amon Düül. It also makes me think about "Shining" creepy OST.
