Zippo Encore recently caught up with a few of the MASTODON guys in Atlanta and discussed among other things, their inspirations, favorite types of music and Zippo. Check out the footage below. MASTODON is currently writing material for its follow-up to 2011's "The Hunter", tentatively due in early 2014. The band wrote and recorded a song for the upcoming animated film"Monsters University".
