I am breaking my musical-interlude-comes-on-Saturday rule to cover an album that comes out today, June 17, 2016
case/lang/veirs is Neko Case, k.d. lang (not capitalized when you are talking about her performances) and Laura Veirs. This is “Atomic Number” from their album case/lang/veirs.
The three women share lead vocals, and the harmonies are great. (I am writing this post at a time when I can’t hear the entire album, and I look forward to hearing the entire thing.)
