As the kids from American Idol 3 tour the country behind winner Fantasia Barrino, the auditions for season 4 kick off this week in Cleveland. The line forms at 6 a.m. on 8/3 with actual auditions taking place at Cleveland Browns Stadium on 8/4. Other cities scheduled for try-outs include St. Louis, D.C., Orlando, New Orleans, Las Vegas, Anchorage, and San Francisco, which winds things up in October. Although the AI focus is on pop singers, the popular television show is a much-viewed platform capable of launching the career of a talented musician. Contestants must be between 16 and 28 years old.
