There are far and few between multi-day music festivals that are housed in one of the Seven Wonders of Illinois. After years and years of concert success, Allerton Park & Retreat Center has decided to up their game. This August, they will present the Prairie Sky Music Festival, a 2-day music festival featuring artists such as: Sam Bush, The Jerry Douglass Band, and more! Festivals have to have food, right? Don't fret. Allerton Park has thought out all these details and will have food vendors, activities, camping and more, all on site!
