This week's From the Top is our All Guest Artist Highlights show featuring some of our favorite moments when celebrity performers have shared the stage with our young musicians. We hear the great soprano Dawn Upshaw sing a beautiful duet by Benjamin Britten with a young baritone. The violin virtuoso Nadia Salerno-Sonnenberg leads a quartet of young musicians in the performance of the Scherzo movement of Schumann's Piano Quartet and entertains all with her signature humor and playfully candid conversational style.
