Orbital

Orbital are an English electronic dance music duo from Sevenoaks, Kent consisting of brothers Phil and Paul Hartnoll. Their career initially ran from 1989 until 2004, but in 2009 they announced that they would be reforming and headlining The Big Chill, in addition to a number of other live shows in 2009. The band's name was taken from Greater London's orbital motorway, the M25, which was central to the early rave scene and party network in the South East during the early days of acid house. Orbital were both critically and commercially successful, and known particularly for their element of live improvisation during shows, a rarity among techno acts. They were initially influenced by early electro and punk rock. - Wikipedia
