The Heritage Hunter Tour was a joint concert tour by American sludge metal band Mastodon and Swedish progressive metal band Opeth.
Opeth and Mastodon each headlined specific concerts.
Ghost was the tour's opening act.
[1][2][3][4] Just prior to taking the stage at the May 7 stop in Maplewood, Minnesota, Opeth's Mikael Åkerfeldt suffered a head laceration requiring eight stitches, forcing the band to cancel their performance that evening.
After a slight delay Mastodon took the stage and dedicated their song "The Sparrow" to Åkerfeldt and Opeth.
