Opeth, Meshuggah, Necrophagist, Cannibal Corpse, Vader, Nile, Behemoth, Suffocation, Cryptopsy, Death, Morbid Angel, etc etc. Used to listen to a lot of black metal bands too when I was younger, but eventually got tired of it and it's philosophy. Satanism is not for me as I am an atheist.(I think so except for atheism cannot explain the origin and scope of the universe.)
Jimi Hendrix, Stevie Ray Vaughn, BB King, etc. Brecker Brothers, Miles Davis, George Benson, John McLaughlin(though I don't understand his music much),
Dream Theater, Joe Satriani, Tommy Emmanuel, Eric Mongrain, Andy McKee, that little asian guy (Junga sth), John Petrucci, Steve Vai, Eric Johnson, Eric Clapton, Tom Morello, guy from opeth(killer riffs), Gordion Knot(awesome band I think), Spastik Ink, etc.......
Deep Purple, Led Zeppelin, Black Sabbath, Iron Maiden, Metallica, Megadeth, AC/DC, Van Halen, Pantera, Slayer, etc etc
Some that popped in my mind right now.
