Kelly Clarkson, Blake Shelton, Jennifer Hudson, and Adam Levine usually sit in the swivel chairs to find America's next great singer, but The Voice judges recently teamed up with The Tonight Show Starring Jimmy Fallon to show off their own vocal chops. Fallon and The Roots joined the coaches in singing a few of their greatest hits — a cappella. The chosen bops included "She Will Be Loved," "Miss Independent," and "Spotlight." It's kind of brilliant how well these separate tracks blended together to create one seamless masterpiece. Watch the video above to hear the full mashup. There's no shortage of talent where these musicians are concerned.
