Michael Franti & Spearhead will release All Rebel Rockers on September 9 via Anti-Records. The follow-up to 2006s politically charged Yell Fire!, All Rebel Rockers was recorded in Kingston, Jamaica, with the legendary team of Sly & Robbie at the helm. Fittingly, the disc finds Spearhead exploring a self-described hybrid dub-infused soul flavor. In addition to core Spearhead members Dave Shul (guitars), Manas Itene (drums), Carl Young (bass) and Raleigh Neal (keyboards), the album also features Zap Mama founder Marie Daulne and Jamaican soul/dancehall star Cherine Anderson. Spearhead will perform with seminal indie-rockers Built to Spill at Bend, ORs Les Schwab Amphitheater on May 23.
