Airs Tuesday, February 21 at 9:00 p.m. The Berklee College of Music in Boston has educated at least eight bandleaders playing this year's Newport Jazz Festival, and several other sidemen. So it's appropriate that the school annually sends one of its most enterprising student groups to Newport. At the Harbor Stage, Puerto Rican saxophonist Mario Castro leads a group of musicians from places as far-flung as South Korea, Israel and California, and as close as a few hours north on the Massachusetts coast. Recorded live at the Newport Jazz Festival on Sunday, August 7.
