Leder Masterclasses

Founded in 2020, this 90-minute masterclass series gives PACO student musicians an exceptional opportunity to work with outstanding professional string players and teachers from around the world.

Past sessions have included individual student musicians working with a masterclass professional and our new format is a professional musician working with our student chamber music ensembles.

    Eugene received his early musical training from renowned cello pedagogue Milly Rosner and completed his graduate studies in cello performance with Barry Gold at UCLA in 1996. He is a member of the San Francisco Chamber Orchestra and an avid chamber musician. He was formerly principal cellist of the Stockton Symphony and a founding member of the Chamberlain String Quartet. His wide range of performance experience has been integral in his background as a music teacher, providing him insights into how to maximize his students’ potential through challenging repertoire choices and strong rehearsal technique.

With the ASQ, Grafilo has made several recordings including works by Brahms, Mozart, Ravel, Schumann, alongside string quartet cycles by Bartók, Beethoven, Kodály and Shostakovich. Prior to joining the Alexander String Quartet, he served as principal second violinist of the Pacific Symphony and concertmaster of the Stockton Symphony.
