Two iconic indie rock acts, Liz Phair and Sleater-Kinney, headline an outdoor show at The Salt Shed Fairgrounds in Chicago. The Salt Shed’s open-air setting provides a fitting stage for Phair’s melodic songwriting alongside Sleater-Kinney’s high-energy, guitar-driven punch. The pairing stands out as a notable co-bill that brings together influential generations of feminist-era rock for a wide regional audience.
