The Graber-Graham-Rose Trio or G-G-R Trio, was formed in 2013 and made its debut performance at Trinity Chamber Concerts in Berkeley. Since then, the group has performed at Old First Church and NoonTime Concert in San Francisco, Throckmorton Theatre in Mill Valley, Four Seasons Arts Cameo Concerts, and other venues. Because works of major composers for this instrumentation are limited, G-G-R Trio also explores arrangements and works by lesser known composers, including Mikhail Glinka, Marko Tajevi, Paul Juon and Gunter Raphael.
