Over seven albums and 18 years, Mastodon has stretched the definition of metal. Co-founder, drummer and lyricist Brann Dailor recently joined hosts Jim DeRogatis and Greg Kot to look back over the band’s career. The conversation ranges from forming in Atlanta to coping with personal tragedy through music. They also couldn’t resist asking how the heck they wound up as wildlings on Game of Thrones. Plus, Jim and Greg share a few of their favorite songs about the devil.
