Chicago-based Purple Apple will open the show, crafting a setlist of chock full of fan favorites, holiday covers and new material. The band is made up of three 15-year-old girls and their twentysomething babysitter on drums. Since the release of their debut EP Sweet Wolverine in 2010, the girls have written more than a dozen new songs and have continued to perfect their live sound, initially at venerable venues like Schubas and The Hideout, and eventually graduating to become the youngest band to ever headline Chicago's legendary rock venue, The Metro. They recently signed a songwriting deal with Sony ATV music publishing and are currently working on a new EP.
