The Voice‘ is returning for its second season in just over a week, and now NBC has released a promo video previewing the exciting blind audition process.

“The entire show begins with these blind auditions,” Christina Aguilera says at the beginning of the clip. “We have no idea what’s going on behind us, and all we can hear are these sort of quiet footsteps … ‘Cause you’re just waiting on pins and needles for what those first few notes sound like.”

Aguilera, Blake Shelton, Adam Levine and Cee Lo Green are all back for Season 2, and they’re more amped than ever before. Judging by the clips of the contestants in this video, viewers won’t be disappointed by what’s in store.

“My favorite thing about the blind auditions is that we never sit there and listen to somebody who can’t sing,” Shelton says. “Everybody that steps on that stage is a great performer.”

Details about the contestants have not yet been revealed, but the new promo video offers a glimpse at a handful of voices that are powerful enough to make anyone stop in their tracks — or turn their chairs around.

In other words, these singers are bringing their A-games. Season 2 of ‘The Voice’ premieres on Feb. 5 on NBC, following the Super Bowl.
