Slappin' on a few tracks off of the great new album by Preservation Hall Jazz Band produced by Jim James and Ben Jaffe of My Morning Jacket on Wednesday's MEDICINE BALL CARAVAN (11am-noon Central Standard on 88.7FM locally orwww.krvs.org). Also: the latest by Shannon McNally (a tribute to Bobby Charles), James Hunter Six, Joe Krown Trio, Dumpstaphunk and David Egan. Got vintage Beau Jocque, James Brown, Tommy Ridgely, Archibald and more, as well.
