Maroon 5+Kelly Clarkson

The headliner and special guest here have been on both sides of a reality singing competition, so they know a thing or two about giving your all in a live performance. Maroon 5, with frontman Adam Levine best known these days as a judge on The Voice, will be joined by original American Idol winner Kelly Clarkson in what may be one of the most pleasant mash-ups of early millennium Top 40 nostalgia. But unlike some of the hitmakers from 2002/2003, Maroon 5 and Kelly Clarkson have remained pop music mainstays who can be counted on to continuously release infectious, catchy, and emotionally charged songs year after year, and that’s something we don’t need a reality competition to prove.
