Hayley Williams teases new solo project Petals For Armor.

Hayley Williams closed out 2019 by sharing a statement where she revealed, "I'm putting out some music next year. With the help of some of my closest friends, I made something I'm going to call my own. It's a really special project and you'll get a taste of it in January."

She's since shared two cryptic video teasers on her social media pointing to a website petalsforarmor.com, with the date January 22nd highlighted as a potential release date, as well as a potential lyric with the caption, “how to draw the line between wrath and mercy.”

There are also street posters for the Petals for Armor project out and about:
