Charlie Puth

Pop singer Charlie Puth originally studied jazz before his YouTube videos turned him into an Internet sensation. Last year, he released his major label debut, Nine Track Mind, a collection of catchy pop tunes that has already yielded singles such as “Marvin Gaye,” a duet with Meghan Trainor that possesses a soulful vibe, and the ballad “One Call Away.” For "We Don't Talk Anymore," a song that features pop singer Selena Gomez, Puth adopts a falsetto and successfully incorporates some synths into the mix. He says he's excited to make his Cleveland debut tonight. "I think I stopped in Cleveland once for a hot dog, but I haven’t spent a lot of time there," he says. "I’m excited to play. The town is really legendary." (Jeff Niesel)
