The network said next month's auditions are intended to find the most talented a capella singing groups to compete on the series.
"There's no lip-syncing, back-up bands or safety net," NBC said in a news release. "They'll be singing for America's vote with the winner walking away with the ultimate prize -- an Epic Records/Sony recording contract."
NBC did not say when the series is slated to premiere.
