Supporting vocalist Brandon Rogers made it to the top 12, and powerful backup crooner Melinda Doolittle has consistently wowed the judges and audience when she takes the spotlight before Simon, Paula and Randy.
But perhaps most intriguing are the ladies behind them: Sharlotte Gibson, Kenya C. Hathaway and Sy Smith. For the past three seasons, they've worked alongside the Fox hit's musical director Rickey Minor to add harmonies and that extra musical oomph sometimes needed by inexperienced "Idol" wannabes.
The backup singers say they've been getting more attention this season than ever before, thanks in part to Doolittle's background.
Watch these videos for an inside look at how they feel they fit into "Idol," how they help contestants, and to listen in on their personal music passions.
In the first video, a singalong interview, Smith interviews the others and they all supply harmonies to the answers.
In the second, the singers describe their role on the "Idol" stage -- a role that often includes vocally rescuing songs gone awry.
In the third video, each artist sings tunes they've written and performed in their still-unfolding, and separate, solo careers: Gibson's "Anything But Yours," Smith's "Aquarius Rising" and Hathaway's "Today's People."
