Pink Floyd - Animals (1977)

Pigs are leaders, sheeps are pawns and dogs are law enforcers. This is another concept album with cryptic lyrics by Pink Floyd. Different from other Pink Floyd's albums, there is no "Time" or "Wish You Were Here" there, so the album has to be heard completely. The track that can be considered a song is the 11-minute "Pigs (Three Different Ones)". B
