Gothic G49240 "The Wannamaker Legacy" is a recording made using a simple pair of omnidirectional mics with superb LF extension. The playing is superb, and everyone should have a copy.
Chandos 9716 "Bombarde" French classics played on the mighty Liverpool Cathedral organ by Ian Tracey is also recorded in a similar manner.
Both recordings are steeped in 32' action, as are Guillou's Dorian recordings at St.Eustache. ( There's a complete works of Cesar Franck and an improvisation disc in that series too)
