I love Alice in Chains.. Pearl Jam and Nirvana are fine too.. but objectively I think Soundgarden was probably the best thing to come out of the Seattle Sound/grunge scene.
You like Alice in Chains? Come on! Tell me another story. lol
I would give the nod to Alice in Chains over Pearl Jam, Pearl Jam has some pretty songs, but they seem so empty, and soul less. Soundgarden would be like Black Sabbath 2.0 in my book. They have some banging songs, but not all their songs are gems.
The only truly bad song by Nirvana is Marigold, written by Dave Growl.
