The Seattle Chamber Music Society is, once again, throwing its Summer Festival, with free informal recitals and full orchestral performances for all ages throughout the month of July. The cabal of esteemed artists involved this year will include Andrew Wan, Jonathan Vinocour, Jeewon Park, Tessa Lark, Yura Lee, and many more. Plus, don't miss the Music Under the Stars series, during which a student ensemble sets up in a park and plays to whoever shows up, often folks with picnic blankets in tow and maybe a surreptitious bottle of wine, after which Benaroya Hall pipes in whatever festival performance is happening that night.
