Tool will temporarily step out of the studio to headline Tempe, Arizona’s Monster Mash festival on Halloween (October 31st).
It marks Tool’s only confirmed performance of 2015 and return to the stage for the first time since embarking on a brief US tour in April 2014.
The lineup for Monster Mash also features Primus and Coheed and Cambria.
