Organist Carl Staplin exploits the grand sound of the 3-35 Dobson tracker built in 1993 at Faith Lutheran Church, Des Moines, Iowa. This unique production precedes each of ten large chorale preludes with a choral performance of the tune sung in English by the 36-voice choir conducted by Eric Dale Knapp. Omitted are the pieces for manual only. Framing the entire performance is the Prelude & Fugue in E-flat, St. Anne.
