As great as they are, the Mumfords are on the verge of overexposure, especially playing the same songs in all their concerts - admittedly the fans want to see them, but I am sure they have other great songs and bring tremendous talent to everything they do. It is great that some lesser known (but also great) bands are brought into the fold in this movie and hopefully get more exposure and recognition, but this would have been the perfect "vehicle" so to speak for the Mumfords to do something different at least in the edit of this film, in not in the concerts along the way.

I love a good concert film and this definitely is one. The variety of bands, venues and songs to the backdrop of the California Zephyr. Chills. Loved it.

I'm not usually a fan of movies about music, but this was fantastic.

This a joyful expression of music and collaboration. If you love music, you will love this film.

goosebumps, the whole film. so good. just want to stomp to some music and learn the banjo. so mind boggling amazing.

I watched the trailer and then rented and wanted it to last longer great music and great to see behind the stage

Amazing. Incredible bands, great energy; I could not stop watching. This documentary gives a behind the scenes look at these fantastic musicians that makes you wish you were on the train with them. A must-watch for fans of these very talented acts.

Good enough to watch again and again. Showed it to a friend who immediately bought it, too!

This was done already in the 60's at least do something new like a convoy of prius's

Incredible!
