Dan Zerfaß plays the Scwalbennestorgel ("Swallow's Nest" Organ) built in 1985 by the Klais firm, and the choir organ built in 1996 by the Oberinger firm at St. Peter's Cathedral, Worms. The Klais organ is situated high on the north wall of the church, in the same place where the church organ sat during the seventeenth century, speaking boldly into the 110 meter long Romanesque styled space. The choir organ was built to supplement the Klais, and is in the style of Aristide Cavaillé-Coll.
