For some, Wilco has become the punchline of a lame joke about music made for settling into 21st century fatherhood. It’s true that the veteran Chicago rock band has a few khaki-Dockers albums in its discography, but 2015’s Star Wars found Jeff Tweedy and company embracing a “less is more” aesthetic: It felt buzzy and squirmy and eccentric and tossed off, in a good way. And Tweedy’s masterful two-night stand at Pickathon was a good reminder that few (if any) humans have written more great songs in the past three decades. Most importantly, Wilco has always been an absolute beast of a live band, no matter how their records sounded. So snicker if you want, but miss tonight’s show at the Schnitz at your own peril. Also, don’t be late: Opener Joan Shelley is a brilliant folk singer whose Over and Even was one of 2015’s best albums. BEN SALMON
