Chicago Open Air

Chicago Open Air was an annual concert held in Bridgeview, Illinois that featured several rock and metal acts. Beginning in 2016, the festival got a lot of recognition as it was Rammstein's only US performance that year. It is held at Toyota Park. Korn debuted the new single "Rotting in Vain" on July 16, 2016 at Chicago Open Air.

The first concert was held from July 14 to July 17, 2016. The 2018 festival was cancelled, but the festival returned in 2019. It was announced via email in late 2019 that the festival was on hiatus for 2020.
