It's a huge weekend for fun, festivals and music in Chicago.
Lollapalooza Music Festival starts Friday. The Office of Emergency Management and Communications say they expect about 100,000 people to attend the event each day. Headliners for Friday night's show include The Black Keys and Black Sabbath. The festival runs until Sunday night.
Friday morning, one of the DJ's from Lollapalooza will spin for us out on the plaza.
Plus, Hard Rock Hotel folks stop by to tell us how to party like a rock star.
Lollapalooza isn't the only thing going on Friday night.
