Mastodon drummer Brann Dailor, alongside keyboardist Core Atoms and keyboardist and vocalist Raheem Amlani, has a group called Arcadea. It's a little bit on the side of a Nintendo-sounding electronica rock band, though there are definitely heavier elements. From what it sounds like here, the group is on the right track to making something awesome!
