With the revival of “American Idol” comes a need for hundreds of new contestants, and Chicago is one of the cities where producers hope to find a potential winner later this summer.

Two buses will cross the country looking for singers, ABC announced Monday, starting with Aug. 17 stops in Portland, Oregon, and Orlando, Florida. A separate open audition is planned in Chicago on Sept. 11, at a venue not yet announced.

Contestants also may apply online, and videos are being accepted now at www.americanidol.com. Singers ages 15 to 28 are eligible.

A year after “Idol’s” run on Fox ended with the crowning of season 15 winner Trent Harmon, ABC announced it is bringing back the competition with a judging panel including pop star Katy Perry.
