Does an artist become one with the music, or is the printed score the final authority? James Conlon and Menahem Pressler team up to explore just who is in charge of a great performance - the composer or the performer - in this look back at the performers featured in the Twelfth Van Cliburn International Piano Competition, held in Fort Worth, Texas, in the spring of 2005. Musical excerpts and rehearsals feature Joyce Yang and the Takács Quartet.
