Philippe Cohen Solal hears a groove as a groove, whether it's a '40s groove, a '70s groove or a modern groove. The French composer behind Gotan Project tests his theory and bridges the time gap by culling jazz, tango, folk, dub and hip-hop united by the sexy, nostalgic mystique of tango's squeezebox, the bandoneon. An untouched work by '70s tango master Astor Piazzolla makes a good starting point. Then Peter Kruder, Anti-Pop Consortium and Pepe Bradock remix Gotan's world-famous musical cocktails, while the Gotan team takes on Chet Baker and Peace Orchestra. Think soundtrack, not muzak.
