Great album Animals! I probably listened to Dark Side 100's of times with headphones & enhancers back in the day. With Animals, the songs flow into the next and is very slow & hypnotic, really pulls you in. I consider Roger Waters THE "Lyric King".
Last count I had 14 of their releases. LOVE Pink Floyd (and post Floyd David Gilmore works as well). A very innovative group to say the least. Poor Syd went down the rabbit hole but he sure left some wild tracks.
I had/have enough on my MP3 player that I could treat my coworkers to a full 8-1/2 hours of Pink Floyd on casual Fridays. And did. Like it or not. ;-)
Same for the Beatles.
Sadly, Stevie Ray Vaughan/Double Trouble didn't make it far enough to fill a day . . . but there you have my three most appreciated groups. Jethro Tull competing with Led Zepplin for #4.
