I found the vynils at home from my parents collection. Did not like it much at first but the cover art was impressive with pictures in pictures. A double lp, Ummagumma. When I bought my first cd it was dark side of the moon. We always put this album when we want to test the sound quality of the sound system. Later I fully got into the early floyd and this is my favourite era with all variations played live in concert. There is no other music like yours. Thank you Pink Floyd.
