London producer and erstwhile Brian Eno weed-carrier Jon Hopkins hit his stride earlier this year with the warmly percolating Immunity LP, which channels Four Tet at the best possible intersection of blissed-out and grounded. But he can also be counted on for proto-dubstep bangers (see 2009's Insides) as much as for tasteful scenery-painting (see his collaborations with Scottish folk singer King Creosote). Fellow British beatsmith Chris Clark has been plying a slightly narrower trade since the turn of the century or so, making exacting and finely textured IDM out of live drum samples and denatured household noises; nonetheless, his is some of the gentler techno-noise to come from the Warp Records camp. His latest release, the remix retrospective Feast/Beast, testifies to the range and inventiveness of his impulse to tinker. Norfolk skygazer Nathan Fake opens.
