The last time I got to see Luftwerk’s magic, it was the zippy video “score” they’d created for an equally zippy piece of contemporary music—”Shunt,” by local composer Mischa Zupko. But another opportunity’s coming up: on February 10, the Chicago-based multimedia team, consisting of SAIC graduates Petra Bachmaier and Sean Gallero, will switch on a site-specific light-and-sound installation at Cloud Gate in Millennium Park. “Luminous Field” will be on view from 6 PM to 9 PM, Sunday through Thursday; and 6 PM to 10 PM Friday and Saturday, through February 20. Check out what they did at Frank Lloyd Wright’s Fallingwater if you want to know why you should stroll by.
