I think it makes a lot of sense. A lot of stage comedians have said that they're "manic" or "high" when they're out on stage doing their thing and then when they're off stage they're depressed and drained. I imagine something similar goes on with musicians. Some people go out and get their favorite food first, but Chris went out and experienced his favorite feeling.The way Chris went was just strange, right after performing he went back to his room and hung himself. I can't even imagine what would make someone do that. You stand there in front of adoring fans and then go back stage and decide you want to take your life?
Worst day EVER I have been playing his music all day. Such a tragedy and totally unexpected. At first I thought it was one of those hoaxes. I wish it had been. Truly a sad day. Layne Staley was bad enough.... but Chris.
Some of the lyrics in audioslave are quite depressing but it's also up for interpretation to the listener.
