Welcome to the world of Pink Floyd, enjoy your stay. Sheep definitely ranks among their best songs.
i've been listening to them for like a month now thx to skill4life. i love their music.
Have you listened to any of their early stuff? To a lot of people it's really obscure but imo it's got as much passion and work put into it as their prog rock.
the stuff with syd? i've listened to one album i think.
the final cut is pretty awesome. when the tigers broke free is the best on that albumhttp://www.youtube.com/watch?v=cFrilwRtvN8&feature=BFa&list=FL16xubperyLb2Durxwuq5Yw
the dark side of the moon is pretty loving awesome too.
