Dragonforce, although their music is assrock, they are very talented musicians. I can roll with Stevie!!!! Great choice.
Kinda impossible for me to do because there are too many talented ones, imo. Thom Yorke, of course. Ben Harper is very talented. Victor Wooten is very talented, as is Flea. Many very technical guitarists like Satriani, Vai, Malmsteen. Most of my favorite musicians were before my time. But as an overall musician I really like Frusciante for his writing ability, guitar playing, vocals, and then his keyboard/piano playing, bass playing, and the way he records his own music and is amazing with effects.
