This family band from a farm in Illinois started out as a songwriting trio after the father of ten and two of his kids were recruited by a Nashville friend in 2007 to help him with a song. The trio has now written several songs for The Band Perry, including their No. 1 single "All Your Life" off their 2012 self-titled album and the title track off their 2013 album Pioneer.

Though The Henningsens often performed their song at open mics in Nashville, they only really considered becoming a band after producer and former record executive Paul Worley (Dixie Chicks, Lady Antebellum) suggested they give it a go.

"We never thought about the idea that we would do this as a group," Clara told Radio.com. "Then we met Paul Worley and he really liked our writing style. He encouraged us to pursue an artistry together. It was kind of weird, because who wants to be in a band with their dad and brother? But he thought that was the genius of it."

Now the trio is out on their own with an EP and a new single called "American Beautiful," which focuses on a girl who's a little unusual and who loves the Rolling Stones.
