Looks like we have our own Peter Parker on board here at CoS. Art Pena is back, and with some mind ripping photos from his recent visit to Chicago’s Millennium Park. Did he just take a nature walk? An architectural tour? Absolutely not. He shimmied on down to the park’s own amphitheater, Pritzker Pavilion, to check out Tucson, Arizona’s own Calexico. Judging from the photos, this set seemed quaint and nominal enough for a balmy September night. And can we say, mariachi band?

Yes, we can.
