As cringe-tastic as these "who's the best at music?!?" threads can be, music being a wholly subjective and infinitely variable art form, and all... they CAN be a good opportunity to discover some wonderful artists. Here are some of my personal favorite guitarists, in case anyone is remotely curious. And FYI, I tend to spend quite a bit on the jazz, fusion, "world music," and art-rock side of things.
John McLaughlin (an all-time hero of mine as a writer and band leader as well as instrumentalist)
Jimmy Herring (guitarist for Aquarium Rescue Unit and his own wonderful groups, toured with John McLaughlin and the Allman Bros)
Kurt Rosenwinkel (his records "Enemies of Energy" and "Heartcore" are well worth hearing)
Allan Holdsworth
Carter Arrington (a dear friend who plays in
my band but also with Kirk Covington, of Tribal Tech fame, they just released an album together!)
John Scofield (another glorious composer and band leader as well as guitarist, my favorite is "Blue Matter")
Several, but not all, of these guys have wheedly-wheedly shred technique that rivals the G3 guys (Herring, McLaughlin, and Arrington) but I'd rather listen to John Scofield than Steve Vai any day. Much respect for Vai, but he doesn't move me like Scofield does. If we all had the same taste in music, film, food, and booze, how much more boring the world would be!
