Oh, those silly Midwest Lutherans! St. Luke's, in Prospect Park, IL, does a lot of things but the most famous may be the St. Luke's Bottle Band. They play bottles of all kinds by blowing on 'em, striking 'em with drumsticks, and so on. It's fun stuff.
There are several RealAudio clips on their website, such as the Second Brandenburg Concerto, the Dance of the Reed Flutes, and a version of one of my top 5 all-time favorite pieces of music, dubbed Rhapsody in Bottles. There are also a lot of concert clips on YouTube: an entire concert, in fact.
Something you'll notice in the concert clips is that the conductor will cue everyone by making a sudden gesture raising his arms. The band members will frequently respond. Keep an eye out for it.
