This DVD provides a rare opportunity to witness two sessions of Carnegie Hall's Robert Shaw Choral Workshop program, featuring rehearsals and portions of performances of Brahm's A German Requiem and Beethoven's Missa solemnis conducted by the legendary Robert Shaw. Follow Maestro Shaw from his initial meeting with the musicians, through the rehearsal process, to the final concert in Carnegie Hall's Isaac Stern Auditorium. Also included in the DVD are Maestro Shaw's invaluable insights into interpretive and performance challenges raised by these two choral masterpieces. The Preparing A Masterpiece video series on the Robert Shaw workshops at Carnegie Hall provides an in-depth look at Maestro Shaw's preparation for performances of choral masterpieces. These workshops inaugurated the Professional Training Workshops, which continue to this day.
