This Sunday night at Grant Park in Chicago, Deadmau5 will raise the curtain on his all-new live show. The occasion is a headline slot at Lollapalooza 2011, closing one of the mainstages, while Foo Fighters take care of the other. In terms of triumphant festival appearances for a dance music act, it’s certainly up there. It should come as no surprise, then, that the tireless tech-geek has been working around the clock to come up with something that’ll top the ‘Rubik’s Cube’ he brought here for Creamfields in Autumn.

“We’re all freaking out. It’s awesome,” the mau5 otherwise known as Joel Zimmerman told Time Out Chicago this week. “Right now we’re working on the actual technology to control all the cool stuff. Otherwise it’s just going to be a lot of expensive stuff up on a stage and everyone’s going to go, ‘Woo… But what does it do?’ But we’re working on it and I think we’ll figure it out. My career depends on it.” Apart from that typically elusive response, there’s not a whole lot more to go on until we tune in on Monday to see the photos and shaky-cam footage.

The other big news for Deadmau5’s rabid fans is the announcement of the finalists in his ‘design the next deadmau5 head’ competition. You can check out the chosen frontrunners in the gallery below, and see the design that won. Or you can just wait to see it on his head at some later date.
