American Idol's Quentin Alexander on His Most Inventive Performances, Wildest Outfits and Favorite Mentor

What do H&M, Annie Lennox and New Orleans “bounce” music have in common? All of them turned out to be integral parts of Quentin Alexander’s American Idol journey.

The Season 14 sixth-place finisher stopped by TVLine HQ for a freewheeling interview about his run on the show — how he managed to convince producers that Adele’s “Rolling in the Deep” fit a “Party Anthem” theme, what process he used to come up with his unusual stage outfits and why he messed with Harry Connick Jr.’s notes midway through his performance of “Are You Gonna Go My Way” (AKA the moment right before the duo’s tense on-camera confrontation).

Also on the docket: Quentin’s failed Season 12 audition, his struggles with pitch throughout the competition, his unique arrangements of “I Put a Spell on You” and “You’re the One That I Want,” his favorite mentor, and his hopes of making a national impact in his post-Idol career.
