Named after Greater London's own circular autobahn, the M25, and central to the early rave scene and party network in the South East during the halcyon 'daze' of Acid House, Orbital have just been announced as headliners of Decibel Festival in Seattle, WA, which will take place on September 26-30. They will be joining an incredible line-up of the best electronic talent from around the world, including the Cannabinoids feat.
