When the bassline comes in on Mainline’s “Black Honey (Who Made Who Remix),” the lead track from Plant Music’s latest label-pimping comp, there’s enough muck and grime coating the notes to knock you on your ass. Then, just when it’s time to dust off and pick yourself up, Champagne’s fist-balling, run-in-place anthem “Mazatlan” powers through the chaos. Basically, the meaty basslines and wacko synth shootouts don’t relent on this one, leaving listeners in a pathetic heap and speakers buzzing for most of the affair.
