Big Easy Express takes audiences on the train that drove the bands Mumford & Sons, Old Crow Medicine Show and Edward Sharpe and the Magnetic Zeroes from Oakland, CA to New Orleans, LA on their Railroad Revival Tour. Unlike the usual practice of separating bands into different, cramped tour buses as they travel between shows, the Big Easy Express allows these three bands to travel together and proves that, sometimes, the journey is better than the destination. With room to move around, an open bar, and a bunch of talented musicians, the jam sessions never end and it becomes hard to tell if the bands are more excited to get on stage and perform for their fans at each stop or get back on the train to perform with each other. As the bands leave the stage, instruments in hand, they become a make shift parade as they walk back to the train, still playing, and continuing to do so the moment they get on board. The music in Big Easy Express is constant as we get an up close look at the various shows performed along the way as well as the music constantly being performed on the train itself. We watch as these musicians learn from each other, trade instruments, write new songs, and slowly (but surely) start to turn into a seamless group of talent rather than individual bands.
