Mr. Rosen achieved international stardom as the first American cellist to win a gold medal at the Tchaikovsky Competition, shortly after winning the coveted Naumburg Competition in 1977. Since then, he has performed with the New York, Los Angeles and Czech philharmonics, the Leipzig Gewandhaus, the Philadelphia, Minnesota and Dresden State orchestras, and the London, Pittsburgh, Seattle, Atlanta, Cincinnati, Indianapolis, Dallas, Houston and Vancouver symphonies. Mr. Rosen began cello studies with Eleonore Schoenfeld and continued with Gregor Piatigorsky. He has recorded several discs on the John Marks label and plays a 1738 Montagnana cello.
