Have you seen Josh doing a very passable Jim Morrison in QOTSA's version of The Doors' Not to touch the earth ? Its on youtube ... probably one of the very few Doors covers i rate.
Yep i include Josh in my list too ... as I would with most 90s guitarists like ...
Josh Homme ... Queens OT Stone Age
Mike McCreedy - Pearl Jam
Kim Thayall - Soundgarden
Chris Cornell - Soundgarden/Audioslave/Temple of the Dog/Green River
Jeff Martin - Tea Party
Tom Morello - RATM
Dave Navarro - Jane's Addiction/RHCP
Jerry Cantrell - The mighty mighty mighty Alice in Chains
John Frusciante - RHCP
Kurdt Kobain - Thats how its spelled on the Bleach album btw - Nirvana
The chicks from the Smashing Pumpkins and White Zombie also rate highly to me
James Hetfield - Metallica is older than 90s but needs listing
man i could be here all day so i'll add one more ... Robert Johnson. He was so good they thought he used black magic to make his guitaring sound so good. All he did was play next to a tape recorder lol.
