FAUST were the first to ever release a clear visible vinyl . That was more amazing , since that first album by this group had a Röntgen-ray-picture of a hand with a fist (faust in german) packed together with the clear vinyl into one visible plastic-cover . That efect was indeed mindblowing . As soon as i saw that one , i had to own it , reagrdless what was recorded on it . In fact it was typical Kraut-Rock in the vein of XHOl-Caravan , early Amon Düül or Kraftwerk . Hardly any music on it , but one nice tune with a young hippy woman saying "Möhren , ich mag Möhren" ( from "Steig Auf Die Leiter") , influenced by Pink Floyds "Marmelade , I like marmelade" on Meddle .
Of course i sold this rubbish a couple years later (to my regret now) . Since i would probably get a fortune for it as it was the first pressing i bought around 1971/early 72 . I never was into collecting stamps ,or paying 10 times the price for a record (often in less good shape or sound) with the 'right number' on it . After all it is the music that counts and unless you actually own the masters you always have a duplicate and not the original . But this is something a lot of us will disagree about .
