The Lumineers tease new song debut for upcoming 'Tonight Show' performance

The Lumineers will be making late-night TV a bit brighter next week.

The "Ho Hey" outfit is performing on NBC's The Tonight Show Starring Jimmy Fallon Thursday, January 13. In a tweet announcing the appearance, The Lumineers teased, "Tune in and you might just hear a new song," suggesting they'll be playing an unreleased song from their upcoming album, Brightside.

The Lumineers have previously released three songs off of Brightside: the title track, "A.M. Radio" and "Big Shot." The album arrives in full on Friday, January 14.

While they gear up to play a new tune, The Lumineers have been enjoying the success of the song "Brightside," which has been the number-one single on Billboard's Alternative Airplay chart for the last three weeks.
