A performance Friday in St. Cloud brings together a Korean folksinger, a Cuban drummer, and a quartet performing beat poetry. "Earth Springs" is the latest in a series of world music showcases in the city. The music the events bring to St. Cloud is far from typical -- and so is the 10-year-old boy who puts them together. Vaji Tomas VA-gee toe-MAHS is slightly more driven than your typical fifth grader. Mainstreet Radio's Jeff Horwich talked with him about his latest concert.
