The Salk Institute for Biological Studies celebrated the 20th anniversary of its Symphony at Salk gala Aug. 29, 2015, under the stars at the seaside research facility in La Jolla. The evening included a pre-concert Champagne reception and dinner, with members of the San Diego Symphony — under the baton of guest maestro Thomas Wilkens — performing a selection of classic works afterward with special guests, trumpeter Chris Botti and jazz guitarist John Pizzarelli.
