Our good friends at Brandeis University are tuning up for the Leonard Bernstein Festival of the Creative Arts. The festival, which will run from April 23 to 26, features folk, classical, African and other extraordinary music and arts initiatives. Aston Magna’s Artistic Director Dan Stepner leads a performance by the Lydian String Quartet, with sonatas by Mozart, Beethoven and Ives. The concert ticket proceeds will benefit the Aston Magna Music Festival scholarship fund, which supports students at the Aston Magna Summer Workshop programs at Brandeis.
