Community Musicworks’ Sonata Series pairs string musicians from the organization with guest pianists. This month’s program takes place in the RISD Museum’s blue Grand Gallery, and features violinist Minna Choi doing Schubert and Sebastian Ruth performing Brahms on viola, both accompanied by guest pianist Eliko Akahori. While you’re there, check out photographer Jesse Burke’s Wild & Precious, which also opens this week. Sundays at the RISD Museum are always free.
