RACHEL MARTIN, HOST:
Good morning. I'm Rachel Martin. When you think Black Sabbath, you think of stuff like this.
(SOUNDBITE OF SONG, "WAR PIGS")
BLACK SABBATH: (Singing) Satan laughing spreads his wings...
MARTIN: Which is why this latest song by the band's guitarist Tony Iommi is getting so much attention.
(SOUNDBITE OF SONG, "HOW GOOD IT IS")
BIRMINGHAM CATHEDRAL CHOIR: (Singing in foreign language).
MARTIN: It's a choral composition he did for the cathedral in his hometown in England. Asked if it meant the 69-year-old had found religion, Iommi said it seemed like a nice thing to do. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
