Detroit gets all the OG techno press, but its Canadian sister across the river, Windsor, Ontario was a hotbed of electronic dance creativity, too. Lauded Plastikman Richie Hawtin hails from there, of course. (He just released a lavish Plastikman 16-CD retrospective accompanied by a coffee-table book called Arkives that recounts the early Detroit-Windsor warehouse scene. Your crazy raver aunt will freaking go nuts for it, www.plastikman.com/arkives.) Now Hawtin's excellent partner in Canadian tech-crime in those early days, John Acquaviva, is getting back into general circulation as well, with a string of well-regarded tunes released this year. He's landing at Mighty with the "we.are.definitive" tour, which pays homage to his seminal Definitive Recordings label, launched in 1993 — look up "House For All" by Blunted Dummies and you'll know what I'm talking about. Joining him for some good ol' Windsor wig-out is current Definitive partner Olivier Giaccomotto. We'll miss original Definitive kid Karl Kowalski, but these two will surely hold it down for the W.
