The battle for Ravinia tickets has begun.
Tickets for the popular summer concert series went on sale at 5 a.m. Tuesday. They can be purchased from Ravinia online, at the box office or by phone.
The most highly anticipated performance by Lady Gaga and Tony Bennett has already been sold out, less than five hours after tickets went on sale. The duo is scheduled to perform June 26 and 27.
Check out the Ravinia calendar for details on which artists are performing and when, and track the status of tickets.
