K Theory took a break from shredding over Gareth Emery mixes to return to some more space-y roots (I think they heard my prayer!).  "Lights Out" is indeed a mind-clearing chillstep tune and in its softer moments it offers a soft ride through plumes of stardust.  It may be too soon to call the stuttery glitches at 2:45 "classic K Theory" but it fits the mold perfectly -- not too disruptive to mellow you out, not too mellow to fire off a few lazers just for fun.
