Preservation Hall was founded in a former French Quarter art gallery in 1961 to give the old players who essentially invented jazz a steady gig. Yet the very idea of preservation runs counter to the nature of improvised music—change was inevitable. The hall has adapted to modernity in part by collaborating with contemporary non-jazz musicians, including My Morning Jacket’s Jim James, a coproducer of Preservation Hall Jazz Band’s latest record, That’s It! (Legacy, July 9). With all original compositions, the album may rattle purists, but the one element it preserves intact is the jubilant spirit of New Orleans music. preservationhall.com.
