'Reacher' Season 3 Ending Song is a 2016 Folk Rock Anthem

Phew! After a massive set of episodes, Reacher Season 3 has concluded with its season finale, "Unfinished Business." Reacher got what he was looking for, and, in an uplifting twist of sorts, almost everybody in the series had a happy ending. 

But as Reacher is taking off on his motorcycle, riding into the sunset, you might be wondering what song is scoring this upbeat montage. The lyrics "Everything will be alright if you let it go" are great, but who sings this song? And where did it come from?
