Mash Up Soundsystem mashes it up in the old-school, soundsystem-on-overdrive-with-messed-up-beats way, and not in the pop-radio-friendly mash-up way. Problem is, what makes for a good live show can quickly become uninteresting on record. You can hand it to them for eclectic beats and tempos as well as funny samples, but at 23 tracks, the album feels incoherent and drenched in distortion simply for its own sake. Something for folks already into the scene but not likely to make any converts.
