Before Blake Shelton's name was widely known in country music, and before he was a judge on The Voice, fans may have seen him opening for Toby Keith's 2002 Shock'n Y'all Tour, Rascal Flatts' 2005 Here's to You Tour or the Flatts' 2006 Me and My Gang Tour. Every superstar starts out as an opening act, after all.

Shelton first headlined his own trek in 2005; it was his Barn and Grill Tour. Other treks have included the Hillbilly Bone Tour, the Well Lit & Amplified Tour, the Ten Times Crazier Tour and the Doing It to Country Songs Tour, among several others.

Shelton's onstage humor, laid-back attitude and well-loved songs have contributed to his star power and helped him sell out venues across the nation. Throughout the years, his stage presence has grown even stronger, his song portfolio has expanded, and his hair has taken quite a turn (for the better, if you ask us). Take a look at the gallery above to see some of our favorite live photos of Shelton.
