Charanga Cakewalk was the opening act. Andy hadn't heard of them either, but as we learned, the "project" was founded by one of the guys in Patty Griffin's band, Michael Ramos. He's basically a keyboard player - piano, synth, melodica, acccordian, etc. Very cool music. Mainly instrumentals. Very neat "groove" - afro-cuban, salsa, reggae, etc.. World beat, I guess. He had a computer/sequencer on stage with him as well as three other live players, and the performances never seemed automated or computerized. Music to make you smile and sway as he put it. A perfect warm-up for the main act. *And Patty Griffin came out for the last song of his set, and contributed some vocals as well as some guiro.
