i think that everyone pretty much has a different perception of what talent is so this thread seems strange to me but i will chime in with bands i dig that are very technically proficient (being that i think that's what this thread is actually about anyways

).
exivious and cynic (although i prefer sean malone on bass)
anything gary willis is in (triphasic, slaughterhouse, etc...)
pat metheny band (always incredible lineups and chemistry)
chick corea (always amazing very much in the same way metheny's bands are)
psycroptic (gets my vote for extreme metal stuff)
opeth (great live band, solid musicianship across the board)
so many dynamos (great live sound, very inventive songwriters, imaginative mix of indie and progressive rock)
maps and atlases (flurries of two handed tapping riffs and interesting ideas all over the place, very complex indie stuff)
