Haim have revealed that they fired their agent after discovering a male artist on the same festival bill as them was paid 10 times more.
The US band – made up sisters Danielle, Este and Alana Haim – opened up about the "insane" pay gap, calling it "f**ked up".
"We had been told that our fee was very low because you played at the festival in the hope that you'd get played on the radio," Danielle told Grazia.
"We didn't think twice about it, but we later found out that someone was getting paid 10 times more than us. And because that we fired our agent."
Alana added: "That's why I love my sisters so much. I trust them with my f**king life. We're all in this together. But it's scary out there and it's f**ked up. It's f**ked up not even to be paid half the same amount. But to be paid a tenth that amount money? It was insane."
The band did not name the festival, though Danielle admitted there's still every chance it might happen again.
"It's so hard to check: everything's so secretive about how much people are getting paid, and that's bullshit," she added.
Haim also discussed the sexism they face as an all-female group in the music industry, with Alana explaining: "What was really scary to us was feeling like if we acted a certain way, people would think we didn't play our own instruments.
"I still get so many people asking me, 'So who really writes your songs?' A lot people automatically accept the fact that an all-male band writes their own songs, but when they see an all-woman band they're like, 'Oh there must be a man behind it, fuelling their fire.'"
