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. Just prior to taking the stage at the May 7 stop in Maplewood, Minnesota, Opeth's Mikael ÃÂ kerfeldt 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 ÃÂ kerfeldt and Opeth.
