We have EDMX, among others, to thank for keeping the old-skool electro candle burning into the future that the genre so ably predicted a quarter-century ago. Armed with a vocoder, Linn Drum machine and a viral sense of nostalgia, Ed leaves none of da rock unturned with some of that clean, straight-ahead future-shock junk á la Grandmaster Flash’s “Scorpio.” Jam on it.
