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?
A lot of Chris's music was rather depressing topically while he was in Audioslave, but there are other songs from his solo career as well that speak of where he was at. From his music it feels safe to conclude that he was in a lot of emotional pain. His life was a weave of turmoil and internal strife. It seemed as though he clung to the idea of himself and what he had done, but the overwhelming dread he felt about the world around him and the fight he had himself really just finally likely got the best of him.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.
