All Fans is Invited to Join as the Extra Haim Bandmate.

"Do you know when you'll be interviewing the band?" an inquiry reads. "I wanted to ask if I can become their extra sister."

There's just one problem: The author likewise desires to be Haim's newest recruit. And we're far from alone. A host of high-profile admirers have openly coveted the role.

One thing is obvious a special quality is happening. Sisters Este, Danielle and Alana started their path performing shows at neighborhood delis with their parents. Today, they are multiple Grammy Award hopefuls.

In the tradition of the greatest bands, they're a close unit. Their music videos frequently show them walking in unison down the roads of Los Angeles. In concert, they perform with such pure joy you can't help but think, "I want to be involved in that, too."

"The numerous instances on tour that young girls approached us and said, 'Watching you live, I bought a guitar'," remarks Alana, the youngest of the Haim siblings. "It is the ultimate compliment. That's an award in itself. We have succeeded if we can encourage young girls to make music."

"So everyone gets an invitation to be the honorary member of Haim."

Historic Nod

The band are speaking from a break, where they're taking a pause after an extensive tour in support of their fourth album, I Quit.

They're currently processing the news it's been in the running for Best Rock Album at the Grammys – with Haim the first all-female band ever in consideration for the trophy.

"I tune into the lists every year, so it almost feels like The Truman Show when your name is called," explains Alana. "I immediately called my sisters to say, 'Did we just hear this right or am I hallucinating'?"

The weight of the accolade isn't lost on the band.

"We deliberately set out to make a rock record this time, so it's a significant step," adds Alana. "Yet we're just appreciative for the women that paved the way."

Emotional Upheaval and Humour

The record emerged from a phase of transition. All three sisters found themselves single, and the music inhabits that strange in-between place where you're happy to be free, but not entirely ready to move on.

The lyrics track breakups and partings. The sisters want love, but not the kind of love they've had. You can hear them working out in real life who they are becoming.

"That's a perfect way of putting it, yes," agrees Danielle. "I Quit is kind of like a personal statement. You have to actively work on blocking the criticism and saying, 'I couldn't care less what people think'."

Evolution of Music

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

For Danielle, who worked on producing the album, that started with the drums.

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

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

Stories and Shared Camaraderie

The band's honesty fueled the album's marketing, where the sisters shared some of their personal tales.

A former partner ended things with Este over a health consideration. Alana told a story of travelling to celebrate New Year's Eve with someone, only to receive a friendly slap at midnight.

"Experiencing these heartbreaks, you just feel like there's no light," notes Alana. "Thus to be able to find humor in those stories and hear others tell you even crazier stories, it's incredible."

A Confident Legacy

It's not difficult sense a shift in the band. Today, Haim are more assured of their place in the music world.

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

However the sister act will always be their number one commitment.

"Me and my siblings have been making music since I was little," shares Alana. "There is no other path that we were meant to do. And I'm really grateful we've gotten here and we're still making music."
