This is an excellent story by Jonathan Kalish of National Public Radio about the american tradition of trombone choirs of all flavors. Interesting to those who are flabbergasted to know such exist and to those of us who play in them.

This story discusses American Moravian-style choirs, the Bay Bones, Emory Remington, Irv Wagner, Jay and Kai, Steve Turre and Gospel trombone choirs.
