In the age of the World Wide Web, jazz is becoming increasingly global, and a new generation of artists—Panamanian pianist Danilo Perez, Argentine pianist Guillermo Klein, Puerto Rican saxophonist David Sanchez—has superbly demonstrated that Latin jazz stretches far beyond the borders of Cuba and Brazil. Singer Claudia Acuna evokes the haunting sounds of her Chilean homeland on her debut album, Wind From the South—but she also demonstrates her affiliation with the post-Motown bop generation via a sparkling cover of Stevie Wonder’s “Visions.” Acuna has a rich voice, full of burnished textures and harmonic surprises. Sometimes, as on “Visions” and “Pure Imagination,” she’s a majestic spirit child; sometimes, as on “Bewitched” and “Prelude to a Kiss,” she’s a love-struck chanteuse. Hear her multitude of influences and personalities coalesce tonight at her Blues Alley debut at 8 and 10 p.m. at Blues Alley, 1073 Wisconsin Ave. NW. $15. (202) 337-4141. (John Murph)
