Anton Zaslavski isn't what you'd call an ordinary DJ. Far from it. Yes, the Russian-German beatsmith is a gifted producer and maestro of the mixers who has rocked unforgettable sets inside numerous nightclubs and at many of the world's top festivals (including Ultra, Nocturnal, and Electric Zoo). But during his musical career, the artist known has Zedd has followed a somewhat curious journey. Zaslavski was classically trained on both the piano and drums as a lad, spent time as a percussionist in a post-hardcore/metal band, and has drawn inspiration from everything from electronic acts like Justice to chamber music when creating his punchy EDM soundscapes. He's also staged some rather unique gigs, the most recent of which was an appearance on The Late Show with David Letterman in January, when he performed a minimalist version of the title track off his latest disc, Clarity, with songstress Foxes on vocals. When Zaslavski brings his Moment of Clarity Tour to the Madison Event Center, 441 West Madison Street, on Saturday, September 21, however, we suspect that his performance might be a bit more electronic in nature, but just as memorable. Openers include fellow European expat Ecotek, indie/nu-disco duo Oliver, and UK electro-house producer Alex Metric. Doors open at 9 p.m. General admission tickets are $50.
