"When I heard the field recording of people milling around Gloucester Cathedral, the choir rehearsing with the organist, I liked to think of the many ghosts that (probably) reside in the cathedral and them weaving in and out of the congregation and choir, possibly into the organ as well, unbeknownst to anyone but themselves. 

"The organ samples have been retuned/detuned against an waltz time drum beat playing against a common time baseline."
