DJ/producer Marshmello will perform his latest single, "Happier," featuring British band Bastille. The record is finding massive success on radio, including holding fast at #1 for a second consecutive week on Billboard's BDS and Mediabase/Top 40 Radio Airplay chart - a first for both artists.

"Hey Look Ma, I Made It" will be the band's next single off the album, and this marks their first time performing the song on national television. Following their performance on the show, Panic! At The Disco will kick off the second leg of their "Pray for the Wicked" Tour in January.

Brynn Cartelli, Season 14 winner of "The Voice," will perform her new self-penned song "Last Night's Mascara" off her forthcoming debut project arriving next year.
