Philip Glass might be the most popular classical music composer of our time.  Sure, he changed the way we think of the words “opera” and “classical composer.” But he’s also been courted by Hollywood, parodied on “South Park,” and used as an answer on “Jeopardy.”  Philip Glass turns 75 today, and he spends part of his birthday with us, including a peek at his newest recording, the Symphony #9.

Tune in to WQXR for a premiere webcast of the Symphony No. 9 on January 31, 2012 at 4 pm. More information here.
