Superb collab between Mr Gasmask and Epidemie (Ketoksid/OB:Cur). A side brings an "Hybrid" as they call it, between trance and Hardtek, supported by an Acid melopopeia... The Flip is a unique peace of Elecytronic Art : a travel into Acid history from the ambient to the HardBeat with some break high time. It's a pure jewel !! One of the biggest tunes i ever heard... MUST HAVE !
