Chicago is already a city with a whole lot of music festivals, but there’s apparently always room for one more. The new Chicago-area festival Sacred Rose just announced the lineup for its inaugural show, which comes to Seatgeek Stadium Campus in suburban Bridgeview 8/26-28. It’s important for any new music festival to have an identity, and Sacred Rose has one; most of its bookings are someone in between the jam-band and indie rock worlds.
