In the late 1980s, as American house and techno imports flooded Britain and the Acid House movement was sweeping the nation, brothers Paul and Phil Hartnoll were busy building Britain's own interpretation of the sound. Named for the illegal "Orbital" raves taking place on London's M1, they dragged their equipment from party to party, playing live PAs of their homegrown dance music to enthusiastic crowds of revelers. Their 1990 single "Chime" was (and still is) the anthem of many a British raver, and their self-titled 1991 debut remains a classic. Opening with the exquisite mid-tempo anthem "Belfast," and containing the "Chime," "Satan," and "Fahrenheit 303" singles, this album captures the innocence and energy of the nascent rave scene.
