I think I read once that he had an almost four octave range. That's probably double the range of most people. Still, the thing that always struck me was how much emotion he could convey in the notes along with his great writing talent.
Absolutely. Chris gave you the feels when he sang. Brilliant singer and always a big fan.
I'm not a pearl jam guy, Alice in chains was ok but a little too much of a depressed heroin junkie feel to me. Nirvana I liked in the 90s but it tapered off a lot, now I only listen to their unplugged album.
