Pat Metheny begins his four-month tour of Europe and the United States this weekend with two performances at Coutances Theater in northern France. Saturday's opener will be the first time Metheny reveals the instruments and magic behind his latest Nonesuch release, Orchestrion. It "sounds really interesting on CD," says Wired, "sort of like a jazz gamelan with an extraterrestrial twist." The Independent hears elements of Nancarrow, Adams, and Zappa in the title track.

Impossible to pigeon hole, and equally impossible to dislike, the Carolina Chocolate Drops are first and foremost musicians" who "refuse to be tied to any one genre."
