If I am not mistaken, that is a picture of Eric Peterson (TESTAMENT/ DRAGONLORD) Steve Smyth has blonde hair and is taller than Eric Peterson. However, both are great guitarist.
~Jeff Loomis! Oh wait lol. I'd have to say Steve Smyth, he tore it up on Dragonlord and the next Testament will surely destroy. Nevermore is lucky to have him. No offense to Tim Calvert, but he played on my least favorite NM album. But I know nothing about Curran Murphy.
