All Fans is Invited to Join as the Fourth Haim Sisters Member.

"When are you interviewing Haim?" a message reads. "I was hoping to ask if I can join as their extra sister."

There's just a single issue: The author likewise wants to be the Haims' fourth member. And we're far from alone. Several celebrated fans have also begged for the honor.

It's clear something is at play. Sisters Este, Danielle and Alana launched their path performing shows at neighborhood delis with their parents. Presently, they stand as repeated Grammy nominees.

Similar to the best ensembles, they're a close trio. Their videos frequently feature them walking in sync down the roads of Los Angeles. In concert, they perform with such unfettered exuberance you can't help but think, "I'd love to be part of that, too."

"The numerous instances on tour that audience members told us and said, 'Watching you live, I picked up a guitar'," states Alana, the youngest of the trio. "That's the biggest honour. That's an award in itself. We've done our job if we can motivate people to start a band."

"Therefore anyone is invited to be the fourth member of Haim."

Grammy Milestone

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

They're presently celebrating the news it's been shortlisted for Best Rock Album at the Grammys – with Haim the first all-woman band ever in consideration for the trophy.

"I follow the nominations every year, so it almost feels like a surreal movie when your name is announced," notes Alana. "I needed to phone my sisters to say, 'Did we just hear this right or am I dreaming'?"

The weight of the honor is deeply felt by the sisters.

"We deliberately set out to make a rock album this time, so it's a significant step," continues Alana. "However we're just grateful for the women that came before us."

Emotional Upheaval and Laughter

The record was born from a phase of emotional upheaval. All three sisters found themselves single, and the music inhabits that unique in-between place where you're glad to be free, but not yet ready to let go.

The themes track departures and partings. The sisters seek love, but not the kind of love they've had. You can hear them determining in real life who they are becoming.

"That's a perfect summary, yes," agrees Danielle. "I Quit is essentially a personal statement. You have to actively work on blocking the noise and saying, 'I couldn't care less what people think'."

Evolution of Music

That recent confidence required a different sonic direction – more raw and direct than any of the music the band had done before.

For Danielle, who co-produced the album, that started with the drum sound.

"Percussion is such a detailed thing, and I care so much about it," she states.

"'Journey of the drum sound' will be the title of our book," jokes Alana. "I always say, our albums don't start until we find the perfect drum sound."

Stories and Shared Laughter

The trio's candor fueled the album's promotional campaign, where the sisters disclosed some of their romantic misadventures.

A former partner ended things with Este over a health consideration. Alana shared a story of travelling to spend New Year's Eve with someone, only to receive a casual gesture at midnight.

"When you're going through these heartbreaks, you just feel like there's no hope," says Alana. "So to be able to find humor in those stories and have them tell you more outrageous stories, it's incredible."

A Confident Future

It's not difficult sense a change in the band. Today, Haim are more certain of their standing in the rock pantheon.

They're major draws, with chart-topping albums and an international fan base.

However the band will always be their number one priority.

"We have been performing since I was four," says Alana. "There is no other path that we were destined for. And I'm really fortunate we've reached this point and we're still making music."
