American Idol's dueling divas topped the ratings Wednesday night, but failed to draw as many viewers as the show's Season 11 premiere.

So they tried again Thursday as Idol aired its Chicago auditions.

They turned up much more talent, featuring 16 contestants who are Hollywood-bound, including Lazaro Arbos, a 21-year-old from Florida who struggles with a stuttering problem but sings beautifully.

Meet Lazaro and the other contestants from Thursday's episode here.
