Afro-Brazilian cool and acid jazz form the outer contours of Cool Hipnoise, a group that combines electro flamboyance with dub flavor. Percussion arrangements range from ostentatious to ultra-urbane, interweaving clava, snare and African gourd sounds. “Dois” evokes Getzian Ipanema and “3 Por Timor” combines bossa nova bass with lilting horns. The populist spirit of dub is redolent in such tracks as “C’Mon Family,” which features The Last Poets, and the swank redux of Nirvana’s “Come As You Are.”
