Chicago’s biggest music fest, Lollapalooza, starts today (Thursday, July 28th). Grant Park will be rocked for 4 days by so many music acts including Metallica, Green Day, and Machine Gun Kelly.

Music lovers not attending the event will actually be able to stream Lolla on Hulu.

Chicagoans trying to avoid the Lollapalooza road closures and crowds will want to avoid Balbo Drive from Columbus to DuSable Lake Shore Drive, Jackson Drive from Columbus to DuSable Lake Shore Drive, Columbus from Monroe to Roosevelt, Ida B. Wells is closed from Michigan to Columbus, and Monroe Street from Michigan to DuSable Lake Shore Drive.
