SMASHING PUMPKINS' BILLY CORGAN picks 11 greatest heavy-metal bands ever

You might not guess it listening to Smashing Pumpkins' grungy, shoegazing alt-rock, but bandleader Billy Corgan is a serious headbanger. After all, he calls Black Sabbath's Tony Iommi "my hero." Revolver recently sat down with Corgan to discuss his Top 11 picks for the greatest heavy-metal bands of all time, and he dug deep, spotlighting everyone from Pantera and Slayer to Mercyful Fate and Rainbow, sharing stories and insights along the way. Watch above.

Smashing Pumpkins' epic new album, Atum: A Rock Opera in Three Acts, is due out in its entirety on May 5th.
