Rodrigo Y Gabriela are two young 20-something (I think, no time to check at the moment!) guitarists that form a two-piece specialising in classical/jazz/rock fusion. With blistering solo runs, intriguing harmonies, innovative use of harmonics and a wonderful percussive style on heavier numbers they prove that classical guitar really can rock. I recommend going to their website and downloading some of the sample tracks here. I met these two in small theatre in my home town of Waterford, Ireland and I think they're both pretty damn fantastic. Check it out.
