Squarehead is back, this time as ES.Q. Not only does he have a gleaming new name, he also has a freshed-up sound after months in the studio perfecting a crisp new audio signature. Tail Winds is a whirlwind of clipped vocal snippets and relentless drums that build an initially air-whipped techy house tune into a track of raw intensity. Over on the flip is Workin' Hard or Hardly Workin', a plaintive vocal refrain wrapped round a thudding and irresistible groove.
