"Take this as me signing this contract - I have agreed to some festivals already that may not adhere to this and I would never let fans down who already have tickets," Healy responded to Snapes' tweet. "But from now I will and believe this is how male artist can be true allies."
Acknowleding that he still needs to work out the specifics of such a contract, he added: "I’m sure my agents are having kittens right now but times up man people need to act and not chat."
The lack of female headliners -- and often, female acts at all -- across major festival lineups has captured attention in recent years. No women will headline Coachella 2020, and when Lizzo was announced among the headliners for this year's Bonnaroo festival, she became the fest's first female headliner ever.
In 2018, 45 music festivals and conferences across the globe signed PRS Foundation's Keychange initiative, pledging to achieve a 50/50 gender balance across their lineups by 2022. In 2019, Spain's Primavera festival had a 50/50 lineup and to date more than 190 festivals have signed the pledge.
Meanwhile, others have responded by creating all-female festivals, like the upcoming GRLS! Festival in Brazil and Femme It Forward's "Love Language" show in Los Angeles.
The 1975's new album, Notes on a Conditional Form, is slated for April 24.
