Simply the greatest band ever. They defy labels and their music defies time. The band rose from relative obscurity to greatness when David Gilmour joined the band, and eventually replaced Syd Barrett. All my favorite Pink Floyd songs involve Gilmour’s guitar work and his sense of music. Waters' lyrics are good, but his real contribution to the group is his perfectionism and his attention to detail. After 23 years, the band re-formed to play for the Live-8 Benefit for Africa concert on July 4, 2005 – a very happy day indeed!

Each of these ladies represent the greatest Pink Floyd albums. From left to right they are:

Atom Heart Mother
Relics
Dark Side of the Moon
Wish You Were Here
The Wall
Animals

Another album that was released during this timeframe is Meddle. According to Wikipedia, the cover of the album is "to be an ear underwater", which may explain why it wasn't painted on the back of a lady for the above artwork.

A Momentary Lapse of Reason
Division Bell
The Endless River

By this time the band was falling apart. They created one more album as Pink Floyd called The Final Cut. But it is really a Roger Waters solo album since the rest of the band felt they had no input and are very disconnected from it. After that Roger Waters departed the band and David Gilmour, Rick Wright and Nick Mason continued on as Pink Floyd and produced three more albums:

Meddle
The Art of Pink Floyd

Pink Floyd has also produced some very impressive art.
