Duke University Chapel, Durham, NC - from the organist's standpoint, this facility is known for three organs: a fine Flentrop, a huge 1932 Aeolian, and a recent Brombaugh organ with a Renaissance flavor. But of course there's a worship life to go with all this, and an archive of online listening.
These programs first came to my attention when someone posted a notice on the mailing list piporg-l that, just after the 9/11 disaster, one hymn interlude in a chapel service seemed to paint a painful picture of the fall of the Twin Towers.
