Here is a video (accessed from this page) of "Evening Prayer at the Basilica" - the Vespers celebrated by the Pope in Washington D.C. this week. Apparently, this is the Crypt Church at that location.
A truly beautiful setting, and some exquisitely beautiful music. (Unfortunately, the announcers seem to want talk over quite a lot of it, rather than letting it speak for itself. And shockingly - at least to this Episcopalian - there is actual applause from the hundreds of Bishops in attendance, when the Pope enters.)
