This irresistible set unfolds a dazzling collage of sounds. Ozomatli have long specialized in an aggressively multicultural fusion of Latin and hip-hop. Now theyve expanded their palette to include Middle Eastern inflections: Believe pulses with Arabic shadings, and Whos to Blame sets an angry rap to Egyptian textures. On a more traditional note, the blazing Nadie Te Tira guest-stars salsa piano legend Eddie Palmieri, and the delicate Santiago features David Hidalgo of Los Lobos. Whether preparing to party on Saturday Night or posing politically charged questions in (Who Discovered) America?, Ozomatli never stray far from an unstoppable beat. Life-affirming music is too often dull, but Street Signs couldnt be more vibrant.
