The World Are Invited to Join as the Extra Haim Sisters Bandmate.

"When are you chatting with Haim?" a message pops up. "I was hoping to ask if I can join as their extra sister."

However, there remains a key snag: The author likewise wants to be Haim's fourth member. What's more, we are far from alone. Several high-profile fans have also petitioned for the role.

The evidence suggests a special quality is going on. Sisters Este, Danielle and Alana launched their career doing sets at small eateries with their parents. Presently, they stand as multiple Grammy nominees.

Like all the best bands, they're a inseparable gang. Their videos repeatedly feature them walking in unison down the streets of Los Angeles. In concert, they play with such unfettered exuberance you inevitably think, "I wish to be involved in that, too."

"How often on tour that audience members approached us and said, 'Seeing you perform, I picked up a bass'," remarks Alana, the most junior of the Haim siblings. "That is the biggest compliment. That's an award in itself. We have succeeded if we can encourage others to form a group."

"So everyone is invited to be the fourth part of the family."

Award Milestone

The group have called into a break, where they're taking a pause after an extensive tour in for their latest album, I Quit.

They're right now reeling from the news it's been in the running for best rock album at the Grammys – with Haim the first female band ever in the running for the award.

"I follow the announcements every year, so it almost feels like The Truman Show when your name is read out," notes Alana. "I had to call my sisters to say, 'Did we just hear this correctly or am I hallucinating'?"

The importance of the accolade resonates with the band.

"We really set out to make a rock record this time, so it's a significant milestone," continues Alana. "However we're just grateful for the pioneers that paved the way."

Heartbreak and Humour

The record emerged from a phase of emotional upheaval. All three sisters ended up single, and the music captures that strange liminal space where you're relieved to be free, but not yet ready to move on.

The themes track breakups and partings. The sisters seek love, but not the relationships they've experienced. You can hear them figuring out in real time who they are becoming.

"I adore way of putting it, yes," says Danielle. "I Quit is like a slogan. You have to consciously practice ignoring the noise and saying, 'I couldn't care less what people think'."

Refinement of Sound

That developed confidence called for a new sound – more organic and powerful than any of the music the band had done before.

For Danielle, who worked on producing the album, that was founded on the percussion.

"Drums are such a specific thing, and I care so much about it," she says.

"'Journey of the drum sound' will be the name of our biography," jokes Alana. "Our motto is, our albums don't start until we find the ideal drum sound."

Experiences and Shared Humor

The trio's candor shaped the album's marketing, where the sisters revealed some of their personal horror stories.

One man left Este over a medical concern. Alana told a story of flying to spend New Year's Eve with someone, only to receive a high five at midnight.

"During these setbacks, you just feel like there's no light," says Alana. "Therefore to be able to find humor in those stories and have them tell you even crazier stories, it's so amazing."

An Assured Path

One can easily sense a shift in the band. Now, Haim are more confident of their place in the music world.

They're top-billed acts, with hit albums and an international following.

But the sister act will consistently be their number one priority.

"We have been making music since I was a young child," concludes Alana. "It's like nothing else that we were supposed to do. And I'm really grateful we've made it and we're still kicking."
