When bands tour together, it doesn't always guarantee they're going to collaborate at the shows. But that wasn't the case Friday night at New York City's Bowery Ballroom when Good Graeff invited their tour mates and headliners, Mates of State, onstage during one of their songs.

The Florida band first entertained the crowd with their bouncy rock – and if you've heard their recorded material, it seems to take on a more lively energy onstage. Playing songs from their new EP, Good Job Go, they brought onstage the husband-wife duo, Mates of State, along with Hey Marseilles' bassist and cellist Samuel Anderson to join them for a song. While it was big party onstage, the instrumentals were so loud that it was difficult to hear the vocals from Brooke Graeff.

Either way, Good Graeff played songs that are easy to jump around to, which can also be said for the night's first act, Hey Marseilles. Hailing from Seattle, the band prove you really can combine rock music, pop melodies and classical strings.

As for Mates of State: Kori Gardner and Jason Hammel just make performing seem so effortless, especially when it comes to switching instruments throughout their set. Playing songs from their latest EP, You're Going to Make It, they also excited fans when they performed their throwback tracks. Although it was the end of a two-month tour, the duo's energy never wavered and, more importantly, they showed the crowd just how happy they were to be playing for them.
