You might not guess it listening to Smashing Pumpkins, but Billy Corgan is a serious metalhead. 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.

Smashing Pumpkins' epic new album, 'Atum: A Rock Opera in Three Acts,' is due out in its entirety on May 5th. --- Subscribe to our channel: http://www.youtube.com/user/revolver?sub_confirmation=1 --- Revolver on the web: Revolver on Shopify: https://revolvermagazine.myshopify.com Revolver on Facebook: https://www.facebook.com/revolvermag/ Revolver on Twitter: https://twitter.com/revolvermag Revolver on Instagram: https://www.instagram.com/revolvermag/ Subscribe to the Revolver Newsletter: https://signup.e2ma.net/signup/1853466/1801978/ #smashingpumpkins #billycorgan #pantera #blacksabbath #metallica #slayer #dimebagdarrel #rainbow #ronniejamesdio #dio #richieblackmore #dokken #mercyfulfate #kingdiamond #grunge #heavymetal #metal #altrock #alternativerock #tonyiommi #accept #judaspriest #robhalford
