'Animals' by Pink Floyd (1977)
After realising that this was the only Waters-era Floyd album I didn't own (and also had never heard before), I bought it yesterday. It really is one of those 'where has this album been all my life?' moments... I literally listened to it all night - I'll probably be sick of it by the end of the week. The first track/side of the album, 'Dogs', is breathtaking - really brilliant, and a total surprise. The rest of the album is excellent as well, but 'Dogs' is something special... I picked up the 2011 remastered version as an 'iTunes LP', complete with full digital artwork/lyrics. Can't believe I've been over-looking this album for so long...
