G3 is an almost annual live music show and concert tour featuring three select guitarists of the generation; hence its name. It was created by guitarists Joe Satriani and Steve Vai in 1996. Since its inception G3 has featured many guitarists including: Yngwie Malmsteen, John Petrucci, Robert Fripp, Eric Johnson, Kenny Wayne Shepherd Band, Uli Jon Roth, Michael Schenker, Adrian Legg, Paul Gilbert and many other special guests, including Steve Lukather, Steve Morse and drummer Mike Portnoy.

There are three official live releases of G3:

Live in Concert (1996)

The 2007 G3 tour line-up lacked Steve Vai (because of his own solo World Tour), and instead consisted of Joe Satriani, Paul Gilbert, and John Petrucci.

G3 is also the name of an, already disbanded, Peruvian hardcore punk band.
