2 Bad Mice formed in England in 1991, and was comprised of Sean O'Keeffe, Simon Colebrooke, & Rob Playford, also owner of Moving Shadow records. 2 Bad Mice was widely credited as among the first UK hardcore acts to begin heavily incorporating breakbeats into their style. They were a staple on the early to mid-90s hardcore scene, and were instrumental in the music's steady mutation into jungle/drum'n'bass.
