Pink Floyd 
"Animals" (Vinyl)

Album #500!

Released in 1977, this album was tucked between the release of 1975's 'Wish You Were Here' and 'The Wall' in 1979.  Perhaps a bit like my generation's Flaming Lips, this album was Floyd's tenth studio album. (To be fair, most people hadn't heard of Pink Floyd until 1973's 'Dark Side of the Moon,' which was already their sixth album.)

Referencing George Orwell's 'Animal Farm,' the songs on this sprawling concept album are loosely correlated to different characters in Great Britain's political arena during the 1970's.
The album wasn't terribly well received, nor has it ever received the same attention as the albums that bookend it.

I won't say this is my favorite Floyd album; I'll bet you this is probably most appreciated by stoners who are able to listen to the track-less sides
