Anyway, Floyd are great. Check out their album "Animals"-- many have argued that is where the distinctive "Pink Floyd" sound emerged, to be refined on such monoliths as Dark Side of the Moon and The Wall.
I cant believe no one else caught this. Sorry Hurin but darkside was well before Animals and its the one thats creditted with the distinctive "Pink Floyd" sound . Animals in actuality wasnt even supposed to be an album. Wish you were here(my favorite floyd album) was supposed to be a double album with animals as the second record. They decided it would be better to split them up and rename the second part Animals. I saw them do the Wish you were here animals concert on the 4th of july at Madison Square Garden in the early 70s and after that roadied for the Wall show at the Nassau Coliesium.

Those four albums I think define the sound of theirs thats most popular and are my favorites. The early Sid stuff was wacked and a trip. You had to do acid to appreciate it. I love Careful with that axe Eugene.
