Thursday's MEDICNE BALL CARAVAN on KRVS (11am-noon Central Standard on 88.7FM locally or at krvs.org) unlocks little secrets to happiness with the sounds of Lost Bayou Ramblers, Violent Femmes and The Deslondes. Also: some X Ray Spex, David Bowie, T. Rex, King Khan & the Shrines, The Brian Jonestown Massacre, Love, The Rose Garden, The Byrds, Quicksilver Messenger Service and The Velvet Underground.
