Weir described the making and collaboration process of Blue Mountain: "When I was 15 I ran away to be a cowboy. I found myself working in Wyoming living in a bunk house with a bunch of old cowpokes and ranch hands, and a lot of those guys had grown up in a era before radio had even got to Wyoming. Their idea of an evening was to tell stories and sing songs. I was the kid with the guitar I was the accompaniment.I learned a bunch of those songs and got steeped into that tradition. It’s a tradition that’s almost gone. I’ve been sort of wondering what to do with that, for decades now. About four years ago, I did a webcast with Josh and a bunch of the guys from of The National. I enjoyed playing with them a bunch. They decided that they liked my cowboy tunes with the Grateful Dead, and proposed a project where we do some stuff like that. That proposal kinda rang my bells."
