san francisco-based producer antiserum steps up for dub police with two unique collaborations, featuring local producers ill-esha and 12th planet respectively. his music is a masterfully crafted fusion of influences that results in a sound entirely his own, balancing light against dark and colour against pure bass pressure. showcasing a deft musicality as well as an unrivalled talent for system shaking productions, antiserum is taking the scene by storm. releases on narco.hz, s.c.u.m and argon amongst others have already propelled him to the forefront of the rapidly growing american dubstep scene, with plenty more still to come. on the a side, he is joined by ill-esha on >zephyr<, a sick g-funk inflected roller. skittering hi-hats and tough drums lay the foundations on this one, with the deep, smooth bass sweeping underneath. the vibrant synths weave in and out of each other with ease, swimming around the mix and swelling expansively through the speakers. on the flip he teams up with 12th planet on the massive >purple & gold<. the g-funk influences continue to flow through this track, pinned down by a hard bassline and taut drums. the shimmering synths sliding over the top of the percussion and off into the atmosphere give the track an epic stop-in-your-tracks effect.
