Ariana Grande/Little Mix/Victoria Monet

Pop singer Ariana Grande has a vocal range that rivals that of Mariah Carey. Her 2014 album, My Everything, received a Grammy nomination for “Best Pop Vocal Album” and delivered the six times-platinum hit “Problem.” Upon the single's release, Grande became “the youngest woman to debut with over 400K sold first-week,” while the song ranked as the fifth “highest digital song debut for a female artist” and ninth highest ever. The tour that brings her to town tonight supports Dangerous Woman, which yielded a massive hit with the title track, a by-the-numbers soul/R&B number that finds Grande seductively crooning. (Niesel)
