Ry Cooder’s Election Special, due out August 21, is a wake-up call as the US heads into the 2012 fall election season. "'Wasting Away in Margaritaville' was a good song in its day," says Cooder, "but we need a different kind of a song now if we’re going to make headway against the likes of Charlie and Dave." On Election Special, which he produced, Cooder plays mandolin, guitar, and bass and wrote all of the songs, co-writing one with Joachim Cooder, who plays drums on the record. Stay tuned for an exclusive Nonesuch Store pre-order offer to come.

The husband and wife team prove that melding popular and traditional music only creates a richer tapestry." The duo will tour North America this summer.
