Lorde seems to be teasing something. At least fans are reading it that way, cause she rarely posts anything not album or tour-related.
I do think she absolutely smashed her headline set in 2022, even tho Solar Power was not her best work, one of my favourite moments at Primavera.
And if they can have The National, Charli and Phoenix back after two years, I don't see why not her with a three year gap, if she has a new album ready.
