2 step was borne out of the Lovers Rock reggae scene in the early 80s and was chiefly a London-based thing - the tunes that were picked up were mainly mellow soul with a beat that roughly corresponded to the reggae otherwise being played by the sound-systems. It is nothing to do with the kind of UK Garage popularised by Craig David, the Modern Soul scene or Steppers scene in Chicago, although some tunes overlap from one to another.
