All Fans is Invited to Be the Additional Haim Sisters Member.

"When are you chatting with the Haim sisters?" an inquiry pops up. "I wanted to ask if I can join as their fourth member."

There's just a key snag: The author likewise wants to be the Haims' fourth member. And we're not alone. Several famous supporters have openly begged for the role.

It's clear an irresistible appeal is going on. Sisters Este, Danielle and Alana launched their musical journey performing shows at neighborhood delis with their family. Now they're repeated Grammy Award hopefuls.

Like all the best groups, they're a inseparable trio. Their music videos often show them striding in unison down the roads of Los Angeles. In concert, they jam with such unfettered exuberance you inevitably think, "I'd love to be a piece of that, too."

"The amount of times on tour that audience members came up to us and said, 'Watching you live, I picked up a guitar'," says Alana, the most junior of the trio. "It is the biggest compliment. That's an award in itself. We've done our job if we can encourage people to form a group."

"And thus all gets an invitation to be the honorary member of Haim."

Grammy Nod

The group are speaking from a break, where they're resting up after an major tour in support of their fourth album, I Quit.

They're presently reeling from the news it's been shortlisted for Best Rock Album at the Grammy Awards – with Haim the pioneering all-woman band ever in consideration for the award.

"I follow the announcements every year, so it almost feels like a surreal movie when your name is called," says Alana. "I had to call my sisters to say, 'Am I hearing this correctly or am I hallucinating'?"

The significance of the nomination isn't lost on the sisters.

"We truly set out to make a guitar-driven album this time, so it's a major milestone," says Alana. "Yet we're just appreciative for the women that inspired us."

Emotional Upheaval and Candor

The record was born from a time of personal change. All three sisters were single, and the music captures that strange liminal space where you're glad to be free, but not quite ready to start anew.

The themes track breakups and partings. The sisters want love, but not the relationships they've experienced. You can hear them working out in real time who they want to be.

"That's a perfect way of putting it, yes," says Danielle. "I Quit is like a mantra. You have to consciously practice ignoring the noise and saying, 'It doesn't matter to me what people think'."

Refinement of Music

That recent resilience demanded a new sound – more unpolished and powerful than anything the band had done before.

For Danielle, who helped produce the album, that began with the drums.

"Drums are such a nuanced thing, and I am so passionate about it," she says.

"'Journey of the drum sound' will be the subject of our memoir," laughs Alana. "I always say, our albums don't start until we find the right drum sound."

Experiences and Collective Laughter

The trio's candor fueled the album's rollout, where the sisters disclosed some of their romantic horror stories.

Someone ended things with Este over a medical concern. Alana recalled a story of flying to celebrate New Year's Eve with someone, only to receive a high five at midnight.

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

A Confident Path

You can clearly sense a change in the band. Now, Haim are more certain of their place in the rock pantheon.

They're top-billed acts, with chart-topping albums and an global audience.

However the sister act will consistently be their primary priority.

"Me and my siblings have been playing music since I was four," concludes Alana. "It's like nothing else that we were supposed to do. And I'm really fortunate we've reached this point and we're still going strong."
