Long before becoming a judge on the U.S. version of The Voice, Blake Shelton was bringing his unique blend of ruggedness and vulnerability to the upper rungs of the country charts. Shelton can send chills up your spine with a spooky story like “Ol' Red” or start the waterworks with the romantic drama of “Go Ahead and Break My Heart", his duet with Gwen Stefani. He can yoke honky-tonk tales to hip-hop grooves or tear off a barn-burning country rocker. But whichever way he leans, everything Shelton does overflows with natural, Oklahoma-bred charm.
