"The Arena" is a 2016 single released by violinist Lindsey Stirling.
The instrumental track was written by Stirling, Hanna and Bird and produced by RUMORS.
[1] In the booklet released with Brave Enough, is a quote from Theodore Roosevelt said to have inspired the song: "It is not the critic who counts; not the man who points out how the strong man stumbles; or where the doer of deeds could have done them better.
The credit belongs to the man who is actually in the arena"[2]"The Arena" features regularly on Stirling's live concert performances, from Brave Enough Tour through to her more recent Artemis Tour.
In a post-apocalyptic, Mad Max inspired environment, Stirling and Hough enter an arena surrounded by crowds and perform an elaborate dance.
