A sprawling example of "world groove," Zap Mama's sixth album is further proof that in these interconnected times the musical world really is shrinking. Born in the Congo and raised in the French culture of Belgium, Zap Mama founder and driving force Marie Daulne  has always ignored the barriers between musical genres like so many outdated speed limits on a dusty highway, but onSupermoonshe dips into so many styles--Afropop, R&B;, hip-hop, funk--as to reduce those barriers to a delightful irrelevancy. Helped by a smorgasbord of big-name collaborators--Me'shell N'degeocello, Tony Allen, and Spearhead's Michael Franti all guest for one track each--Daulne turns African pygmy music into a rollicking club anthem on "Gati," borrows James Brown's "Payback" guitar riff on "Toma Taboo," uses the intricate polyrhythmic arrangement of "Go Boy" for a touching tale of an African immigrant, and evokes modern soul singers like Macy Gray on the title track. Through it all, the intricate vocal arrangements and production that are Zap Mama's trademark--performed largely by Daulne herself--never fail to astonish.--Ezra Gale
