Backstreet Boys

Backstreet's back (alright!), but then again, the beloved boy band never really left, save for a short hiatus in the early-aughts. Touring in support of its 10th studio album, DNA, the harmonizing vocal group blend peppy R&B balladry with tracks that take a stab at more contemporary styles, touching on everything from EDM to synth-pop. Those seeking some late ’90s nostalgia won't be disappointed—tracks like "I Want It That Way" and "Quit Playing Games (With My Heart)" are mainstays of the group's setlists.
