For 15 years, Mastodon has been one of America’s most consistent bands, whether they’re making concept records based on Moby Dick or catchy hard-rock anthems in the mold of classic bands from the 70s and 80s.

It hasn’t always been easy — the making of the band’s latest LP, Emperor of Sand, was marred by personal tragedies and hardships suffered by all of the members. Steve talks with the band’s drummer and lyricist, Brann Dailor, about how Mastodon has thrived and survived for so long in this special bonus episode.
