Sandbox Percussion brings a concert of innovative new music to San Antonio this weekend

Sandbox Percussion's name calls to mind a creative playground activity: digging in the dirt, molding it into complex architecture and smashing it in a frenzied climax when the whim strikes. Percussionists Jonathan Allen, Victor Caccese, Ian Rosenbaum and Terry Sweeney collaborate with composers as well as artists in other disciplines to craft performances that go beyond toe-tapping rhythms — though there's always plenty of that too.
