Suppose Ill give this a go!
Guitarists, I will just name the ones who inspire me, and whose work I find myself constantly coming back to, learning, and comparing my work to:
Dimebag Darrel (R.I.P) (PanterA)
Steve Morse (Solo)
John Petrucci (Dream Theater, LTE)
Dave Mustaine/Marty Friedman (Megadeth)
Jeff Hanneman (Slayer)
Guthrie Govan (Solo)
Mark Morton (Lamb of God)
Joe Pass (Solo)
Andy McKee (Solo)
Vocalists, I will name the vocalists I really cant get enough of, in terms of lyrics and singing ability:
Corey Taylor (Slipknot)
James LaBrie (Dream Theater)
Randy Blythe (Lamb of God)
Eva Cassidy (Solo)
Yeah I know mst of them aren't metal, but now that I've typed all that out im not bothered changing it.
