It’s a US band and I saw it on youtube early 2017, I think (before April).
The band is i think a trio, definitely at least 1 guy and 1 woman, but i think 2 guys (maybe they are related, but I might be remembering wrong… maybe the band name was something about being related).
The genre is modern folk?
The video was weird. It’s a bunch of head shots of the 2-3 band members, only one person shows at a time, as they sing the song. I think they were all on a roof. And as they’re singing stuff flies around them / into their faces+hair. I forget exactly what the things were, but maybe paint or feathers or ?
