Three years after Vol.4 :: Slaves of Fear, the L.A. trio's ferocious entry into the world of heavy music, Health return with the second half of their Disco4 series. A whole lot went to hell in the world in the meantime, forcing the band to re-invent how they wrote music together. For Disco4 :: Part II they cut it fast and mean, recruiting both legends and nascent contenders of heavy music and its many peripheral genres. Cold Blood's blistering heaviness juxtaposed against album cuts like the raucous "Pagan Iconz" (with noise-rap banshee Backxwash and the virtuosically scabrous trio Ho99o9) or the contemplative "Still Breathing" (co-piloted with teenage post-punk experimentalist Ekkstacy), demonstrates the breadth of Health's sonic palette and ability to incorporate what heavy music looks like today and going forward. Health are not only making the heaviest, most genre-obliterating music of their career. They're documenting just how insane it feels to be alive right now.
