The Chemical Brothers have always boasted an inspired range of collaborators from Beth Orton and Noel Gallagher to Tim Burgess and The Flaming Lips. Here, Kele Okereke takes time out from one of this year's big success stories Bloc Party to lend vocals to this pounding number.

Okereke's vocals of "I wanted to believe" become ever more urgent as the song progresses and there's a good range of effects and tricks from the boys throughout. It'll appeal equally to the indie crowd as well as old school dance fans, which is of course the genius of The Chemical Brothers.

Look out too for the fantastic video which accompanies the song featuring car assembly robots which come to life and attack people - not quite up there with the Aphex Twin's Come To Daddy in terms of unsettling pop promos but certainly getting there.
