by Jason AnkenyWhat sets Chocolate Supa Highway immediately apart from the previous album Home is its sound -- boasting a murky, bass-heavy atmosphere clearly influenced by the rise of trip-hop, the album lends Michael Franti's politically-charged raps a cinematic distinction missing from his previous efforts. Spanning from R&B-textured urban grooves to jagged rap anthems, Chocolate Supa Highway is no less challenging or confrontational than its predecessor, but for the most time Franti's music bears an importance equal to his message.
