Ok, that song was really good. I love mellow jams like that.
That album came out when I was 14. My tastes have changed a lot since then. I was into Pearl Jam, Bad Religion, NOFX, Nine Inch Nails... I liked Primus but apart from that I just liked fast music back then.
Maggot Brain was the closing track on "Ball Hog or Tugboat" by Mike Watt, which came out in 95 and went largely unnoticed, probably because the first single from the album was the worst song on the album. Watt invited just about every musician he knew to come over and they wrote the album in the studio collaboratively. I think Maggot Brain is the only cover.
The album features members of Pearl Jam, Nirvana, Foo Fighters, Red Hot Chili Peppers, the Beastie Boys, Henry Rollins, Sonic Youth, Dinosaur Jr, Black Flag, The Pixies, Circle-Jerks, The Lemonheads, The Screaming Trees, The Meat Puppets, That Dog, Nels Cline... It's a really good album imo, lots of variety, but it's wasn't as good as you'd expect from a super-group like that I guess.
