Dubstep years are even more cruel and abbreviated than dog years, so O.G. maestro Pinch is practically like the Zeus of this shit, with releases stretching all the way back to 2005.
"Retribution" is the first half of a 12" old boy just dropped on Swamp Records. I don't even know how you'd call this stuff dubstep anymore and, indeed, the official sales page just lists it generically as "bass music". Good enough for me.
