This is Mason Proper as remixed by MC Jack in The Box on the Remix Fight! website. Sometimes the remixes on Remix Fight! are mangled beyond recognition and enjoyment, sometimes they are greatly improved. This is a case of the latter, of course.
While the original (available on Mason Proper’s MySpace page) is quite good, I found the music a bit muddy. MC Jack in The Box has punched up the instruments a bit and clarified the vocal wailing into a more coherent tune that is worth repeated listening.
