This is just ~ a music video.
I honestly don't know why I love this so much. It's a trailer/promo for a full-length documentary of a bunch of artists who hiked the full length of the John Muir Trail together over 25 days, absorbing it and reflecting it back as art. But I think this is actually better than the film. And the song is great. And the idea of being out on the trail with friends, etc.
