Last month, the country superstar Miranda Lambert got together with her songwriting partners Jack Ingram and Jon Randall to release the album The Marfa Tapes. This was a total one-for-me passion project. Lambert and friends recorded themselves sitting around a campfire and playing songs that they’d just written in the roughest possible form — singing and playing acoustic guitars for one single mic, outdoors, with ambient noises creeping in and with no second takes. The album is great, and it also sounds like it was a lot of fun to make. It also seems like it’s a lot of fun to promote.
