Ryan Adams, Jason Isbell: “Love in the First Degree”

“At the end of this song, we should both get a free toolbox,” Ryan Adams joked the other night in San Francisco as he and tour opener Jason Isbell’s cover of 1981 Alabama hit “Love in the First Degree” strayed from a faithful rendition into tongue-in-cheek territory toward the coda. Their take does justice to both Adams’ humorous and heartfelt sides quite well, but the biggest highlight for me is simply hearing their voices harmonize after months of watching the pair’s bromance blossom on Twitter (Isbell also joined Adams for “Come Pick Me Up” and a Whiskeytown song). Thanks to this clip, you can stream decent audio of their duet above.
