Check out Rodrigo y Gabriela's self titled album, released earlier this month. They're an acoustic duo that plays with more thunder than most electric acts out there. And they should, since they cut their teeth playing in a heavy metal band at the start of their careers. On top of that, the scope of their influence ranges from their roots in Mexico to perfecting their pairing for the last few years in Ireland. I saw them earlier this year in San Francisco and was blown away (the first Mexican/Irish accents I've ever heard, at that). Between his surgical playing and her incredibly percussive playing, they create a sound that's pure candy to the ears.
I probably sound like a mole for the band, but it's really just good stuff. Easily my favorite strings album since Rite of Strings from '95 by di Meola, Clarke, and Ponty. Pretty nicely mixed, too, but not the cleanest. Perfectly adequate, though. Very highly recommended. And if you get a chance to see them in concert, definitely a must-see.
