"132 Ranks for Pipe Organ was composed by Olivia Block in 2016-2017, as a commission for LAMPO and The Renaissance Society. Block composed the piece specifically for the enormous Skinner Organ at Rockefeller Memorial Chapel in Chicago. The world premiere was performed by Block on April 21, 2017. The concert, free and open to all ages attracted a large crowd. 132 Ranks was conceived as a hybrid of concert and sound installation. Six speakers were placed throughout the chapel. These speakers played white noise, sine tones, and prerecorded organ sounds, designed to interact acoustically with the live performance, and bring out the acoustics of the chapel in unconventional ways. White noise and low bass tones pulsed and sliced through the air, while sine tones and organ clusters created complex beating patterns and inner ear sound phenomena. Audience members were participants, quietly walking through the majestic, dimly lit chapel. Listeners noticed how the acoustics, materials and shape of the space altered the live and recorded organ sounds as Block performed. Some audience members relaxed on the floor of the chapel, listening, while others explored the upper balconies and hallways. 132 Ranks was designed to emphasize the architectural qualities and unique sonic and spatial capacities of the Skinner Organ. The piece included both the lowest pedal notes, felt in the body, as well as the highest bell tones, played at extreme dynamic levels. At times, sounds were isolated in discrete locations to emphasize the chapel's shape.Olivia Block is an American composer and media artist.

"Built with the Chapel itself in 1928, Rockefeller Chapel's regal organ is one of four University organs built by the great American organ builder Ernest M. Skinner in the pre-Aeolian Skinner years (the others being at Yale, Princeton, and Michigan). These four organs are considered among the finest examples of 20th century romantic organs built in America.

In the Rockefeller organ, Skinner fully invested his genius for realizing a full orchestral sound, with a complete collection of voices and many soft ethereal effects. Many of the large pipe scales, which are necessary to achieve a full sound in a building the size of the Chapel, are no longer built and thus cannot be found in contemporary organs. The original Chapel organ included four manuals, and had 6,610 organ pipes in 108 ranks; following its 2008 restoration, it has 8,565 pipes in 132 ranks. Its bay of pipes, located in the chancel, is a work of art in itself and is an integral element of the interior architecture of Rockefeller. In addition to the chancel organ located at the front of the chapel, Skinner installed a gallery organ in the upper balcony of the Chapel, to accompany the gallery choir. The organs can be played independently or as one, using either console.

Rockefeller's organ was unveiled at a recital by Lynnwood Farnam, reportedly to a crowd of over 2,500 admirers, on November 1, 1928. It has been played by many great organists of the 20th century, including a series of recitals by the great Marcel Dupré."-University of Chicago, Rockefeller Memorial Chapel website
