Opens Friday 4/13: Choreographer James Sewell has a great love and knowledge of music -- he studies it with seemingly the same fervor as dance. The next two weekends, James Sewell Ballet and the Schubert Club present a repertory favorite, "Opus 131" (pictured, with Sally Rousse), set to Beethoven's challenging String Quartet in C-sharp minor, performed live by the Grammy Award-winning Parker Quartet. Complexity and structure intertwine through movement and music in a work celebrating the beauty within relationships and rule-breaking. The program also features "A Sound Embrace," a world premiere by Sewell pairing elements of Argentine tango and improvisation. A sneak peek this year revealed a work that draws upon passion and humor to create an unexpected yet effective partnership. (8 p.m. Fri-Sat., 2 p.m. next Sun. $10-$32. Ends April 22.
