Happy Halloween, rockers! Two years ago, Maynard James Keenan and the guys of Tool celebrated Halloween by dressing up as Led Zeppelin for their only scheduled performance of 2015.

On Oct. 31, 2015, the band dressed as the members of Led Zeppelin and opened their set at Tempe’s Monster Mash with a cover of Zeppelin’s song “No Quarter.” Now that is a Halloween memory to keep close to your heart.

 At that show, the group also performed “The Grudge” for the first time with Keenan since 2002, and they debuted a new instrumental song named “Descending.”
As for this year, the guys of Tool recently wrapped up a batch of North American tour dates. Now, Keenan’s other band, A Perfect Circle, is getting ready to hit the road on a fall tour. They perform Wednesday (Nov. 1) Fairfax, Virginia.
