For one unforgettable night, the Salt Shed will give lucky audience members the chance to live out the ultimate rock star fantasy - or nightmare, depending on your perspective -  on one of the city’s biggest stages. Presented in partnership with the Empty Bottle – the legendary and long-running live music room – this momentous occasion will be hosted by Chicago karaoke veterans Ryan Murphy and Amber Mueller, with singers chosen at random through an on-site sign up process. Additional select performance slots will be a chance to rally for selected non-profits. So RSVP (it's free, people!) and get ready to belt out a hit. Wow the crowd. Become a Chicago legend.     RSVP DOES NOT GUARANTEE ADMISSION
