This year's Resonance Festival, the second annual, features some performers well worth anybody's time. Luca Mundaca is a guitarist and singer born in Chile, but raised in Brazil, whose music blends samba, jazz, and folk. Simon Shaheen, an Arab performer who's collaborated with Bill Laswell in the past, plays the violin and the oud (a lute-like instrument), combining traditional Middle Eastern melodies with jazz and classical music. And there will be plenty of drumming too, from a pair of African percussion troupes to a group playing Trinidadian steel pans. So haul your ass down to Ohio City, and hear some sounds that are brand-new . . . to you, that is.
