The Atlanta Symphony Orchestra Chorus was founded in 1970 by former Music Director Robert Shaw and comprises 200 auditioned voices. The Chorus is an all-volunteer organization that performs on a regular basis with the Orchestra and is featured on many of its recordings. Led by Director of Choruses, Norman Mackenzie, the Chorus is known for its precision and expressive singing quality. Its recordings have won 14 Grammy Awards (nine for Best Choral Performance; four for Best Classical Recording and one for Best Opera Recording). Those include Vaughan Williams' A Sea Symphony and the Berlioz Requiem. The Chorus performs large choral-symphonic works under the direction of Music Director, Robert Spano; Principal Guest Conductor, Donald Runnicles. In addition, the Chorus has been involved in the creation and shaping of numerous world-premiere commissioned works. The Chorus made its debut at Carnegie Hall in 1976 in a performance of Beethoven's Symphony No. 9 with the Atlanta Symphony Orchestra, led by Robert Shaw. In addition, the Chorus performed in Washington, DC, for President-elect Jimmy Carter's Inaugural Concert in 1977. In 1988, it accompanied Shaw and the Orchestra on their European debut tour. The Chorus has traveled to Germany three times as a special guest of the Berlin Philharmonic – in December 2003 for three performances of Britten's War Requiem, in May 2008 for the Berlioz Requiem, and in December 2009 for a week of Brahms Requiem performances – all with Atlanta Symphony Orchestra Principal Guest Conductor, Donald Runnicles. Within the Chorus, there is an auditioned group of 60 singers called the Atlanta Symphony Orchestra Chamber Chorus. The Chamber Chorus, which formed before the larger Chorus in 1967, performs music of the Baroque and Classical eras, as well as works by modern masters. ------------------------ As Director of Choruses for the Atlanta Symphony Orchestra since 2000 and holder of its endowed Frannie and Bill Graves Chair, Norman Mackenzie was chosen to help carry forward the creative vision of legendary founding conductor Robert Shaw to a new generation of music lovers. At the Orchestra, he prepares the Choruses for all concerts and recordings, works closely with Robert Spano on the commissioning and realization of new choral-orchestral works and conducts holiday concerts annually. During his tenure, the Chorus has made numerous tours and garnered its most recent four Grammy awards. Mr. Mackenzie also serves as Organist and Director of Music and Fine Arts for Atlanta's Trinity Presbyterian Church and pursues an active recital and guest conducting schedule. The New York Times describes Mackenzie as Robert Shaw's "designated successor." In his 14-year association with Shaw, he was keyboardist for the Atlanta Symphony Orchestra, principal accompanist for the Choruses and ultimately assistant choral conductor. In addition, he was musical assistant and accompanist for the Robert Shaw Chamber Singers, the Robert Shaw Institute Summer Choral Festivals in France and the United States and the famed Shaw/Carnegie Hall Choral Workshops. He was choral clinician for the first three workshops after Shaw's passing, and partnered with Robert Spano for the 20th anniversary workshop featuring the Berlioz Requiem.
