Allegri: 'Miserere' (Westminster Abbey Choir)
The interior of the Sistine Chapel was the only location were Gregorio Allegri's Miserere was allowed to be performed.
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.
