Ethan Shanfeld The last time the Strokes played Chicago’s Metro was in 2001. The band’s debut album “Is This It” was just a few months old, but it had already launched Julian Casablancas and Co.

to indie stardom. The now festival anthem and sports arena staple “Reptilia,” which would bring them to new heights, was two years away.Two decades later, the Strokes returned to the 1,100-cap Wrigleyville venue in support of local politician Kina Collins’ congressional run.

Collins is a 31-year-old progressive activist whose platform includes fighting for unions, universal healthcare, body autonomy, gun control and climate solutions. (“Sorry to the Republicans in the crowd,” moaned Casablancas midway through the band’s set.) Opening the night, Collins delivered an energizing speech that touched on her core issues. “I’m running for Congress because we need representation that gives a damn about us,” Collins said, eliciting roars from the audience. “The congressman I’m running against has been my congressman since I was five years old.”Collins said she met Casablancas at a house party in New York, where the two apparently hit it off and Collins convinced the singer to perform a “concert for the hardworking folks across the Midwest who are doing what they need to do to elect progressives.” The concert was originally planned for May 30, before voter registration closed, but a COVID case within the band led to a postponement.
