After teasing their fans with a “Wait for it…” announcement, the news is finally out: Tool will be headlining the Monster Mash Halloween concert in Phoenix, AZ! They’ll be performing alongside Primus and Coheed & Cambria, making for one exception night of metal-twinged music.

The lineup poster also promises special guests TBA, so we’ll be sure to update you once that announcement has been made. Tickets for the show will go on sale this Friday, at 10 AM (presumably Mountain Time), via the Monster Mash website.

The full ‘Monster Mash’ festival includes performances from Santana, Tedeschi Trucks Band, and John Fogerty on Friday October 30th, as well as sets from Linkin Park, Rob Zombie, Deftones, Ghost, and Halestorm on Sunday November 1st. Check out the poster for the Tool annonucement below:
