Earlier this month, Williams covered Phoebe Bridgers' "Smoke Signals" as a tribute to her friend/photographer's late father.

Yesterday (14 April), she shared another cover on Instagram, this time a version of Tegan and Sara's "Call It Off", which features on their 2007 LP The Con.

Williams writes, "amateur hour / self-serenade. My strings are old, i have no pants on, i felt like playing this sad song. "Call It Off" by the pals Tegan and Sara."

Last week, Williams unveiled "My Friend", another preview of her forthcoming debut solo LP Petals For Armor.

Hayley Williams' Petals For Armor album arrives 8 May via Atlantic Records, and is available to pre-order now.
