The grizzled bros of My Morning Jacket will play Koka Booth Amphitheatre in Cary April 30 with The Preservation Hall Jazz Band, after a tour-anchoring stop in New Orleans for Jazzfest. MMJ frontman Jim James (Yim Yames?) recently recorded two tracks for PHJB’s new album, PRESERVATION: An Album To Benefit Preservation Hall & The Preservation Hall Music Outreach Program. The nine-show run starts in Alabama and ends two weeks later in Ohio.
