Monday's badass MEDICINE BALL CARAVAN broadcast (11am-noon Central Standard on 88.7FM locally or www.krvs.org) blasts beams of musical audio from the likes of the late, great J.J. Cale, Los Lobos, Rolling Stones, Steve Earle, Valerie June and the Nubian oud master named Hamza El Din. Also: one more sneak peek at Brother Dege's upcoming release.
