The Chemical Brothers are an English electronic music duo formed by Ed Simons and Tom Rowlands in Manchester in 1989. They were pioneers in bringing the big beat genre to the forefront of pop culture.

Big beat is an electronic music genre that usually uses heavy breakbeats and synthesizer-generated loops and patterns – common to acid house/techno. The term has been used by the British music industry to describe music by artists such as The Prodigy, the Chemical Brothers, Fatboy Slim, the Crystal Method, Propellerheads, Basement Jaxx and Groove Armada.
