Never liked Soundgarden. Thought there were a couple good Audioslave tracks. Not much to say about Chris. I think there are better lyricist and singers from that era in my opinion. Oh well, nice article.
I'll give you the lyricist part, since that's totally subjective, but I feel like there really aren't many singers better than Cornell. The guy is a vocal monster.
I'm not even a big fan, mind you. But the dude has a killer voice.
