The top 13 will become the top 12 on 'American Idol.' One will be sent home tonight after performing for 'This is Me' night, choosing a song that defines them as an artist. Several artists defined themselves as country artists, but it was Ben Briley who had the country moment of the night, singing Johnny Cash's 'Folsom Prison Blues.'

Ben Briley

Ben Briley honored the Man in Black on what would have been his 82nd birthday with 'Folsom Prison Blues.' Although judge Keith Urban thought Briley got a little lost in the song at points, the performance received positive reviews. It was the best country performance of the night for me and was more than enough to keep Ben around for another week for four.

Before his performance, Briley admitted to Ryan Seacrest, social media is something new for him. 'Instagram? What happened to Polaroid cameras?' To get started, Briley and Seacrest took a 'selfie.' Welcome to the social media world Ben :)

CJ Harris

CJ Harris recevied mixed reviews for his performance of Darius Rucker's 'Radio.' Although Harry Connick Jr. liked the song, he didn't think it was the right song choice for CJ. Keith disagreed. I love CJ and Keith Urban, but I had to agree with Harry. The performance was good, but it wasn't great. It should be enough to keep him around for another week though.

CJ's fans loved the performance. One even asked Darius Rucker to stop singing the song.

Dexter Roberts

Dexter Roberts opened the show with Chris Young's 'Aw Naw.' It was another average performance. The song choice just didn't showcase Dexter's voice. However, I doubt he'll be sent home. The ladies love him.

Caleb Johnson

Resident rocker Caleb Johnson, closed the show with the performance of the night. He sang 'Pressure and Time,' a song I'd never heard, but it didn't matter. He had the audience and two of the three judges on their feet.

In case you were wondering about Keith's shirt, which seems to get just as much buzz as the Idol performances, it said co-independence. Keith even tweeted a picture, to show his fans.

Who do you think will be sent home tonight? Tune in to Fox at 8 to find out.
