Chamber music lovers in the Bay Area will recognize the names of Kati Kyme, Anthony Martin, Joseph Edelberg and Thalia Moore, four fine string players with a long string of affiliations and performances. They join together in a chamber group they're calling String Circle and, at the Walt Disney Family Museum, they'll present a concert of Henry Purcell's Suite from The Fairy Queen and Schubert's Quartet in G Major, D.887. There are so many good tunes on this concert, you'll have a tough time deciding which ones to hum on the way out.
