Thursday's MEDICINE BALL CARAVAN (11am-noon Central Standard on 88.7FM locally or anywhere at www.krvs.org) spends one last day dipping our toes into 45-year old mud with more historic live performances from 1969's Woodstock Music & Art Fair. Closing out with sounds of the Butterfield Blues Band, Ten Years After, Santana, Sly & the Family Stone and Jimi Hendrix.
