American Idol Exclusive Video: Get a Sneak Peek of the Top 15 Guys at Randy Jackson's Workshop!

Briston Maroney learns about not looking “goofy” with his guitar. Caleb Johnson tries to appear less “angry” while singing (a Chris Daughty protip!). And Dexter Roberts gets to work on “Dexterfying” every tune he covers.

These are just a few of the takeaways from the following exclusive video previewing tonight’s installment of American Idol (8/7c on Fox) — in which we’ll see the Top 15 guys dive headlong into Randy Jackson’s Idol Workshop, and then hope their efforts make them one of the 10 contestants the judges will choose to perform for America’s votes.
