If there’s one thing that’s certain about Mastodon and The Dillinger Escape Plan, it’s that they tour incessantly. If there’s one thing that’s certain about Max Cavalera, it’s that he’s almost always working on an album, whether it’s with Soulfly or Cavalera Conspiracy, or side projects like Killer be Killed. It’s because of the schedules of those three, as well as former The Mars Volta drummer Dave Elitch, that getting the four members of Killer be Killed together is, if not an impossibility, at least something that takes a ton of scheduling. Google Play got them together for an interview a few weeks ago, and now Kerrang has unveiled the video for the album’s “Wings of Feather and Wax,” which corraled them into a room to play together. Take a good look, since it could be a long while before you see Cavalera, Troy Sanders, Greg Puciato and Elitch together in the same room again. It doesn’t hurt that the song’s really good, either.
