One tidbit in the great New York Times interview with Hayley Williams is that Boygenius will be on her upcoming album:

One of her confidants, the singer and songwriter Julien Baker, said she and Williams were bonded by “being raised culturally Christian in the South then coming into the world” of music. “She has an innate connection with the deeply emotionally profound and really wants to explore those things in an honest way with people,” Baker said in a phone interview. “But also she is a uniquely disarming person.” Baker, Phoebe Bridgers and Lucy Dacus — the trio boygenius — provide backing vocals on a “Petals for Armor” song about “wilted women” moving toward the light.
