Simpson's songs have netted praise from all corners: The Huffington Post wrote, "I can't think of a better description for Simpson, whose original off-the-wall undertakings are reminiscent of the whimsical and whip-smart work by David Byrne, Jim James and the Decemberists' Colin Meloy." Allmusic.com adds that Bryan's songwriting suggests "a more sanguine, Fun-loving Father John Misty."
After a genre-spanning career that has included making his own records as a singer/songwriter with multiple Grammy winners Dan Auerbach of The Black Keys and bluegrass giant Ricky Skaggs, touring and recording with British folk-rock phenoms Mumford and Sons, and having penned several Billboard chart-topping hits like Blake Shelton's "A Guy with a Girl," Tim McGraw's "Better Than I Used to Be," and Joe Nichols' "Yeah" – there is no doubt that the 19 year old who stormed into Nashville with his hillbilly instruments in one hand, and a batch of tunes in the other, had any idea all the places his musical journey would take him. A journey Simpson believes he's "just getting started on."
The words of John Newton best express Bryan's mission for his songs, "I thank the Lord if He makes my writings useful. I hope they contain some of His truths; like a torch, may be seen by its own light without reference to the hand that holds it."
