If you've ever seen Classic Albums by VH1 they made an episode (rightfully) dedicated to the making of DSOTM, and boy did they really put a lot into that album and were meticulous even down to their backup singers and all of the sound effects and everything. It really was the culmination of everything they put into their more spacey albums up to that point with a little funkiness and a little hard rocking which is what makes it so dynamic. I'll have to find it it's an interesting show. They also made one for A Night at the Opera Ms. Queen Fangirl.
Sigh all I can do is open a bottle of beer and play Pink Floyd.
That is the one thing I would change in my past, learn piano or guitar.
My favorite Pink Floyd albums in order :
Animals
Wish You Were Here
Meddle
Dark Side of the Moon ...and the underrated
A Saucerful of Secrets
My favorite is Echoes, it touches a little bit of the best of them all!!
