Paul Barbarin, Punch Miller's Bunch
"Jazz at Preservation Hall III" (Vinyl)

Atlantic Records recorded legends of Dixieland jazz for a week in July of 1962, releasing a total of four volumes of music from the heart of New Orleans' jazz scene.

This specific record was made over two nights. Paul Barbarin recorded on July 5th. Punch Miller recorded on the 6th.
The artists were not young when these records were made; I would liken it to the resurgence in popularity of blues artists like Muddy Waters, John Lee Hooker and the like in the 60's when a young generation of rock n' rollers discovered them.
This feels like an archival project of sorts, but the recordings are great and the musicians play with as much energy and vigor as they ever did.
