Metric @ Radio City Music Hall, 2012 (more by Jonathan McPhail)
Metric

As mentioned on BV, Red Bull Sound Select is throwing 10 free concerts and 10 cities all which are happening on the same weekend (July 26 & 27). Chicago is one of those cities and is getting Metric at House of Blues on July 27 with "showcasing sets" from Gemini Club and My Gold Mask. Tickets are free but you need to request them. Good luck.

Other concerts in this 10-city series include Gaslight Anthem in NYC and The Dandy Warhols in Austin.
