As the 50th anniversary of the recording and release of both Cream's "Wheels Of Fire" and Led Zeppelin's debut approaches, we spin from both on Thursday's MEDICINE BALL CARAVAN on KRVS (11am-noon Central Standard on 88.7FM locally or krvs.org). Also: the latest from The Record Company and Aimee Lay next to tracks by The Raveonettes and classic spins from David Bowie, Leon Russell & Marc Benno, Bob Dylan and Spirit.
