Dalton Rapattoni on His Idol Triumphs ('Sound of Silence,' 'Bird Set Free') and His Decision to Come Out as Bipolar

Dalton Rapattoni says his past experience in the boy band IM5 definitely helped him during his third-place run on American Idol‘s farewell season — but not for the reasons you might expect.

“I already knew how to talk to people in the music industry,” Dalton says during his three-part video interview with TVLine, so not only was he able to stand up for his creative ideas when meeting with producers, he also knew to be respectful to key advisors during stressful situations.

Dalton breaks down his approach to some of his best moments on the show (including the emotional release of “Bird Set Free”), explains what went wrong during “Radioactive” and “Everybody Wants to Rule the World,” and reveals the song he was thwarted (twice!) from singing during the live rounds. Plus, we hear more about the week he wavered between “Seven Nation Army” and “God Only Knows.”

If that’s not enough for you, Dalton also delves into the reasons he never considered keeping his bipolar disorder from the viewing public, and shares his plans for a post-Idol future.
