From big-beat origins to woozy psychedelic detours, The Chemical Brothers' restless spirit never lets them stand still for long—and it's reflected in their taste of remixers, too. Over the years, they've invited artists from across the spectrum—progressive house, nu-disco, hard techno—to put a fresh (and often underground) spin on their work. No matter the style, the Chems' killer hooks ring out loud and clear.
