Allegri's Miserere Featured on NPR

Found out about this music discussed on NPR from here.

Here's NPR's description:

All Things Considered, March 16, 2008 - Composer Gregorio Allegri's "Miserere" is a piece of choral music so powerful that a 17th-century pope decreed it could be played only during the week leading to Easter--and then only in the Sistine Chapel. Jesse Kornbluth of HeadButler.com talks about the "Miserere" with Jacki Lyden.
