Municipal Waste and High On Fire were slated to tour together as "The Speed of the Wizard" tour. Unfortunately, High On Fire will not be joining the tour. Singer/guitarist Matt Pike had a medical emergency and had to get a partial toe amputation. The band stated, "Matt has a medical emergency culminating in the partial amputation of one of his toes. The scheduling of this procedure is immediate and the recovery time will overlap our intended tour with MW. We will unfortunately be unable to participate in this tour but will be back stronger than ever in 2019!” Municipal waste will continue with the tour. High on Fire released Electric Messiah earlier this year.
