O'Callaghan, in between songs, gave out water bottles to a sweaty audience, took a selfie with a fan’s phone and handed a guitar pick to a girl who asked for one. Logan Reidsma | Asst. Photo Editor

O'Callaghan constantly asked the crowd questions and talking to them in between songs. He also made them laugh by telling jokes, such as how The Maine was going to play covers of songs by Demi Lovato. Logan Reidsma | Asst. Photo Editor

Brock called the night "one of the sweatier shows of the tour," but the stuffy environment didn't faze any of the acts or the audience. Logan Reidsma | Asst. Photo Editor

Drummer Brian Blake played with Real Friends, a band that had an edgier, punk-rock sound. The crowdsurfing and moshing was more extreme during Real Friends' set than that of Knuckle Puck. Logan Reidsma | Asst. Photo Editor

Joe Taylor, lead singer of the Chicago-based band Knuckle Puck, thanked the crowd several times for coming to the concert. It was the group's first time playing in Syracuse. Logan Reidsma | Asst. Photo Editor

Bass player Garrett Nickelsen's enthusiasm was obvious as he jumped around onstage while playing with The Maine. He never said a word to the crowd but his energetic behavior showed he was having fun. Logan Reidsma | Asst. Photo Editor

O'Callaghan talked to the crowd on multiple occasions. At the end of the night, he and the other members of The Maine spent at least an hour talking to fans who waited for them, signing CDs and taking selfies. Logan Reidsma | Asst. Photo Editor
