London dance duo Groove Armada consists of Tom Findlay and Andy Cato. The group formed in the mid-'90s after being introduced by Cato's girlfriend and soon started their own club, also named Groove Armada (after a '70s discotheque), which featured their spinning. By 1997 they released a handful of singles, including "4 Tune Cookie" and "At the River"; their debut album, Northern Star, followed the next year. 1999 saw the release of Vertigo, which made the Top 20 of the British charts and silver status in the U.K.
