Agree. My favourite would be Piper at the Gates of Dawn which unlike their later stuff is pop stuctured with a subconscious profundity rather than 'profound' music that is just pop at heart. And speaking of the Tangerine Dream influence, witness this quirky gem:http://www.youtube.com/watch?v=sK_TnlFNnCM
Great! Piper is certianly arresting.Are you suggesting that it is more profound than their more famous offerings?
