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. One of the biggest names in British electronica during the 1990s, 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. In 1989 Orbital recorded "Chime" on their father's cassette deck, which they released on Oh Zone Records in December 1989, and then re-released on FFRR Records a few months later. The track became a rave anthem, reaching number 17 in the UK charts and earning them an appearance on Top of the Pops, during which they wore anti-Poll Tax t-shirts. A few singles and EPs followed, and their first self-titled album, a collection of tracks recorded at various times, was released in late 1991. In late 1992, the Radiccio EP barely reached the UK top 40, but it included one of their most popular songs, "Halcyon". This song featured a sample of Kirsty Hawkshaw from "It's a Fine Day" (a chart hit for Opus III earlier that year), and B-side "The Naked and the Dead" was similarly based on a line from Scott Walker's rendition of Jacques Brel's song "Next". "Halcyon" was dedicated to the Hartnolls' mother, who was addicted to the tranquiliser Halcion (Triazolam) for many years. The duo's popularity grew rapidly with the release of their second self-titled album, in 1993. The album featured complex arrangements and textures, and opens with the two-minute track "Time Becomes", consisting of nothing more than two slightly detuned, looped samples of a Michael Dorn line from Star Trek: The Next Generation, "...where time becomes a loop" being played simultaneously through the left and right channels, respectively (until one cycle of phase difference has happened). This same sample was used at the beginning of "the Mobius", the opening track in the previous album. This audio pun was intended to make listeners believe that they had bought a mis-pressed album (Orbital 1 packaged as Orbital 2). The album reached #28 on the UK album charts, staying in the top chart for 15 weeks. "Halcyon" was remixed for the album, as "Halcyon + On + On". Versions of this song played live by the band have incorporated diverse samples, including "You Give Love a Bad Name" by the band Bon Jovi, "Heaven Is a Place on Earth" by Belinda Carlisle, and most recently "I Believe in a Thing Called Love" by the band The Darkness. The first two albums are commonly known as "The Green Album" and "The Brown Album", after the colours of their covers.
