In preparation for his concert on Friday, John made this delightful video introducing the Marion Camp Oliver Organ in Thomsen Memorial Chapel—constructed and installed by Paul Fritts of Tacoma Washington in 2003. John talks about its sounds, mechanism, temperment, decorative carvings, and more, concluding with a full performance of a brief prelude by Buxtehude. It's 25 minutes, but feel free to jump around—the Buxtehude starts around minute 21.
