“Our next guests are a Grammy-nominated rock and roll band from Atlanta, and I won’t lie to you, I’m frightened,” Letterman said, introducing Mastodon on their first-ever  late night TV performance back in 2009. He must not have been that scared, though, as he’s had them back once again for each album. “Curl of the Burl” sounded particularly good.
