There was a tribute page that someone had done for Layne, set to Wail & Wasp, one of my favorite songs from them (Cantrell). It appears to be gone, but it was extremely well done. There were pics of him as a kid and from shows, with friends, etc... It very nearly moved me to tears. A buddy of mine is from Seattle and actually met him once in a thrift store. He said he was a very "normal" kind of guy.
Cantrell is a key part of their music as well. His subsequent band, Damage Plan, suffered another horrible loss. They were a LOT heavier, even heavier than early AIC, but with that same characteristic guitar of Cantrell.
