Atlanta's Mastodon appeared on Jimmy Kimmel Live last night to play "The Motherload" from their latest album Once More 'Round the Sun. Watch the footage below.

Once More 'Round the Sun debuted at #6 on the Billboard Top 200 chart after it's June 24th release and marks the second time Mastodon debuted in the Top 10.

The band is known for their concept album about Moby Dick and trademark combination of sludge and progressive metal, which now seems to be acquiring a bit of a poppy edge to it.

The band is currently finishing off a few festival appearances before they head out for a full headlining U.S. tour with support from France's Gojira and Norway's Kvelertak.?
