Josh Groban brings his rich baritone to The Colosseum at Caesars Palace with GEMS, a residency that lets him settle into one room and dig into a catalog spanning nearly two decades. Known for blending classical training with pop sensibility, Groban's voice has a way of filling a space without needing to shout—there's a warmth to it that translates well live, whether he's leaning into an operatic swell or easing into something more stripped-down and intimate.

The Colosseum itself, built with Celine Dion's residency in mind years ago, has become one of the better rooms in Vegas for this kind of show—big enough for a full production but still designed so you feel close to the stage. Expect a set that moves between his radio hits and deeper cuts, likely with some orchestral backing given his background, and a night that leans more toward listening and feeling than typical Vegas spectacle.
