It's that time again! Tonight—from 8:00 to 10:00 PM, live on FOX—this season's American Idol Top 9 will perform for the judges' critiques and our votes. Want in on the action? Your open thread is inside.

There's not much to say about tonight's episode besides what we've already gone over: nine finalists, each singing one song from the Rock and Roll Hall of Fame. The episode lasts two hours and will air live on FOX. Ryan Seacrest hosts, and the judging panel consists of Steven Tyler, Jennifer Lopez and Randy Jackson.
