Previewing the June 22 John Vanderslice-Magik*Magik Orchestra “Davies After Hours” performance (after the San Francisco Symphony performs Bela Bartok’s “Duke Bluebeard’s Castle”), Minna Choi and Annie Phillips talk about Magik*Magik’s many collaborations and share some of the group’s original music and orchestrations. (Symphony tickets, including the Davies After Hours performance, will be given away to three lucky KPFA listeners.)
