This four-man collective-featuring the talents of Stakka, Friction, Skinny and K Tee-continues on in the rolling sci-fi vein these producers love so well. “Music For the Masses” and “Electrolux” are relentless, pounding Amen crushers, while “Low Key” and “You and I Know” are swingy machine-funk with precisely placed female vocals. Considering drum & bass’s current warmth, these tracks sound a bit austere, but they’ll still have some dancefloor currency.
