In April 2011, the band joined Mumford & Sons and Old Crow Medicine Show on the Railroad Revival Tour. According to American Songwriter, the tour stopped in six cities, playing alternative venues such as an Austin, Texas high school where Mumford & Sons taught the marching band how to play their hit "The Cave". The tour was also the subject of Grammy-nominated director Emmett Malloy's latest documentary Big Easy Express, which strove to capture "the pure joy of music" through Americana folk imagery.[8] The documentary went on to win in the category for Best Long Form Music Video at the 2013 Grammy Awards. In 2011, Railroad Revival Tour bands Mumford & Sons, Edward Sharpe and the Magnetic Zeros, and Old Crow Medicine Show together closed their shows at every stop with "This Train."
