Country Jam unveiled all four of its headliners and put tickets on sale for the 28th annual festival this morning, with country music superstar Luke Bryan at the forefront of the 2019 lineup.

Bryan, Sam Hunt, Little Big Town and legendary band Alabama will headline each night at Jam Ranch from June 13-16, 2019.

Next year's headliners boast a combined 20 No. 1 albums, 58 No. 1 singles, 29 Academy of Country Music awards and 18 Country Music Association Awards.

This will be Luke Bryan's debut at Country Jam. One of country music's biggest names, Bryan is on a streak of four consecutive No. 1 albums and 13 No. 1 singles, including his latest "Sunrise, Sunburn, Sunset."

Hunt is one of the biggest breakout artists in recent memory. His 2017 hit, "Body Like A Back Road," spent 34 weeks at No. 1 on the Hot Country Songs Chart and is certified five-times Platinum.

To date, Hunt has had six singles reach Platinum status.

Little Big Town broke out on the scene in 2012 with their smash single, "Pontoon," and have followed with hits such as "Tornado," "Day Drinking," "Girl Crush," and "Better Man." The foursome has won Vocal Group of the Year at the ACMs each of the last four years.

Alabama needs no introduction. The most successful country band of all-time, Alabama has sold more than 75 million albums and more than 40 No. 1 singles.
