Sour Boy, Bitter Girl has been around, in some form or another, for a long time now. It started as a song writing moniker and, through a very long series of loose and tight collaborations, developed into a dark indie pop band who prefers things right on the verge of chaos. They released The Palm Reader & The Palm Writer at the tail end of 2017 and spent much of 2018 working on new material. Maybe they'll play some of that.
Existential Dread, Yeah?
