The latest in a line of socially and politically active East Los Angeles groups stretching back through War and El Chicano, Slowrider respect the sound of their forebearers while updating it with bilingual MCs and space-funk atmosphere (think Lonnie Liston-Smith in Havana). Down to six pieces from the nine-piece combo that released Nacimiento and toured with Ozomatli, their third album is a mixture of new tracks and remixes. The sound is tightly rhythmic, with horn flourishes countered by darkly introspective tracks like “Misconceptions” and “Acid Reign” adding their production skills to a stark and effective balance between string-laden dirge, beatbox and tongue-twisting rap.
