NES Cover bands: Minibosses, The Advantage, Xoc, Virt, Project X, etc...
Rock, etc...: Buckethead, Megadeth, Steve Vai, Joe Satriani, Stevie Ray Vaughan, Huevos Rancheros, Dick Dale, The Ventures, Jason Becker, Dream Theater, The Hellecasters, Paul Gilbert, Racer X, Al Di Meola, John Williams' movie scores, Impellitteri, etc...
The overwhelming theme of most of the stuff I like is the guitar.
I'd say that on a whole, my tastes are pretty eclectic.
