The de Young Museum will host some work-in-progress events with Glorious Ravage musicians this summer as part of its hugely popular Friday Nights at the de Young series. On Friday, August 7, we will play some site-specific improvisations in Wilsey Court, and create new structures for improvisation based on paintings in the museum’s J.M.W. Turner exhibition. On Friday, August 21, we will perform in the museum’s James Turrell skyspace, Three Gems.
