DUDE... WHAT A COVER.
King Ultramega is a new super group composed over William Duvall from Alice in Chains, Bill Kelliher from Mastadon, Charlie Benante from Anthrax/Pantera, and bassist Mark Menghi. To show some love to Chris Cornell, they covered the Soundgarden classic "Rusty Cage."
Honestly, insane. So heavy and William's vocals fit right in. It's no original, but it's pretty damn good.
