If someone would have told me he would sound this bad in 2002 when I saw him in concert, I would have said, "No shit. He sounds bad enough now."
One of the worst shows I've ever seen. His backing band sang an unhealthy chunk of the songs for him while he spoke half of the vocals and then did these weird high step pseudo kicks. He humped a bottle of jack daniels and spilled some of it on the front row and started insulting some guy saying that he was going going him with his woman.
Somehow I doubt the guy felt threatened at all.
Then Sammy Hagar went on, who I'm not a huge fan of, and put on an amazing show.
