Country Jam Colorado continues to grow bigger and bigger. Tim McGraw has just been announced as the first headliner for the 2015 Country Jam in Grand Junction, Colo.

McGraw brings his catalog of 35 (and counting) No. 1 hits to the most exciting and dependable country music party in America. With a new album called 'Sundown Heaven Town' scheduled for release in September, the ‘Meanwhile Back at Mama’s’ singer is the perfect artist to headline the music and camping festival.

Turnout for the 2014 festival was up, with Brantley Gilbert, Lady Antebellum, Eric Church and Jake Owen headlining. Each day was filled with half a dozen country stars, and the venue held more once-in-a-lifetime opportunities.
