Head case

Think of Joel Zimmerman as a modern-day Superman or, maybe, a musical Mighty Mouse. He’s a thin, mild-mannered, 30-year-old Canadian until he dons his trademark helmet and becomes Deadmau5, the brilliant underground electronic musician who’s elevated the style with whirling, intricate compositions.

Deadmau5 is scurrying out from the underground this year with a series of major gigs that have included a critically praised Lollapalooza performance and the MTV Video Music Awards. This week he’s booked for an unprecedented six-night, sold-out residency at the Roseland Ballroom starting Tuesday.

The music is obviously in his head, but his head is in one of the most outrageous headdresses ever worn onstage. Zimmerman likens it to “a Maserati sitting on my head.” And it’s inspired his audience too: “Dude, I’ve seen thousands of fan-made heads. It’s crazy insane and f—ing hilarious. I love it.” Here’s what’s between Deadmau5’s very large ears.

* “The basic head is a hollow acrylic dome. The Jim Henson Company makes them for me now. There are a bunch of different versions. I’m on No. 9 right now.”

* “There are seven mushroom fans built into the back of the head. It’s powered by an electronic umbilical cord that also sends in audio and video signals.”

*“It has a video component in it that projects images from a server. It’s very sophisticated. It’s a spherical video system that lets the face on the head [show] expression.”

*“When I look out, I’m not looking through holes, but into a pair of video goggles.”

*“It’s about 10 pounds, but after an hour it starts to weigh on me. There’s a harness that holds it in place.”
