Layne Staley and Jerry Cantrell could harmonize like nobody else. That was such a unique sound. Layne's vocals with Mad Season were awesome too. Layne, yet another incredible talent the world has lost to suicide :-(. Sorry...Robin Williams on my mind... :-(.
Maynard it incredible too. I'm a huge Tool fan too!
My skill stops with the guitar too. In my high school garage band, I distinctly remember the moment that my best friend and bandmate came over and took my microphone away from me while we were playing My Generation! I'm sure I could learn, but I've never really had the desire.
