After a break for the holidays, the Showdown returns with a surprise two-day champion taking on a star who got his start in the rock world. The Henningsens' 'American Beautiful' beat both George Strait and Miranda Lambert's singles to get a chance to take on the latest from Darius Rucker today and tonight on Taste of Country Nights radio.

'American Beautiful' is the debut single from the family trio from Illinois, and it's quickly finding fans on the radio. The upbeat new single introduces a fresh voice in Clara Henningsen. Her dad and brother back her up on the lead single.

Rucker has released 'Wagon Wheel' as the second single from his upcoming album, 'True Believers.' The cover of the popular Old Crow Medicine Show song features Rucker's lablemates, Lady Antebellum.

Listen to clips of both the Henningsens' and Rucker's songs and vote for your favorite here. You can vote once every hour online, so come back and vote often to be sure your artist wins. Hear the full versions of the songs tonight after 10PM on Taste of Country Nights. Help your favorite song win by placing additional votes at (888) 678-9995. Call as many times as you like! You can listen to the show online through any of the 41 radio stations that carry it. Voting will end tonight at 10:40PM CT.

Showdown Rules: The song with the most votes wins, and the winner goes on to face a new challenger in the next Showdown.

If a song wins five days in a row, it will be retired into the Taste of Country Showdown Hall of Fame to allow for new songs to compete. Some songs will be considered for a second Showdown if voter turnout is healthy in a losing effort.
