The early hip-hop beats and ancient synthesizers that once instantly signified hard electro are everywhere these days, so Satamile Records is betting more ears are primed for real electro than ever. E.M.S. brings unrelenting beats and time-tested robotic vocoders to the dancefloor, but a lack of the variety and humor makes this eponymous album seem a bit redundant. Dublin’s Decal takes Two Lone Swordsmen as his model, letting more blips and buzzes bounce around Release Through Velocity. The decayed tunings and the restless spasms of In “Defense Of…” and “64 Guns” will stay fresh long after the currency of your local electroclash night expires.
