300 Spring St., Jeffersonville
$10; 8 p.m.
Music has always been a powerful force for social justice. This weekend, concerts across the country are being held to defend the separation of church and state. Sponsored by Americans United for Separation of Church and State, these concerts will raise awareness and funds necessary to help the fight for marriage equality and reproductive rights. Louisville’s show is Friday and features singer-songwriter Steff Mahan at 300 Spring in Jeffersonville. Mahan has opened for the Indigo Girls, Patty Griffin and Tift Merritt, to namedrop some notables. More than 100 musicians are participating nationwide, and the effort will culminate in Los Angeles with a concert featuring Sarah Silverman, Russell Brand and more. Do it for your country. —Sara Havens
