All Time Low‘s Alex Gaskarth joined blackbear onstage for a live performance of “Monsters.” The performance took place during the Dallas show of blackbear’s current run supporting Maroon 5.

Monsters,” featuring Demi Lovato and blackbear, was All Time Low’s first No. 1 radio hit. The track garnered several award nominations, including the 2021 iHeartRadio Music Awards’ Alternative Rock Song of the Year and Top Rock Song for the 2021 Billboard Music Awards.

All Time Low are currently on tour as part of Sad Summer Fest, with their own individual concerts scheduled between dates. Earlier in the day (Aug. 16), Gaskarth tweeted about having the day off in Dallas. blackbear’s response suggested they would be seeing each other at his show that evening.

During the show, blackbear ushered Gaskarth to the stage with their collaboration playing in the background, immediately jumping into a short yet fiery performance.
