Everyone is Invited to Be the Fourth Haim Sisters Member.

"Any idea when you're speaking to the band?" a message arrives. "I wanted to ask if I can become their fourth member."

However, there remains a key snag: The author likewise wants to be the Haims' newest recruit. Furthermore, we are not alone. Multiple high-profile fans have publicly begged for the honor.

One thing is obvious something is going on. Sisters Este, Danielle and Alana launched their musical journey performing shows at local delicatessens with their parents. Today, they are multiple Grammy Award nominees.

Like all the greatest ensembles, they're a close unit. Their music videos often feature them striding in unison down the streets of Los Angeles. On stage, they perform with such pure happiness you can't help but think, "I'd love to be part of that, too."

"How often on tour that young girls told us and said, 'Watching you live, I bought a drum kit'," states Alana, the youngest of the trio. "That is the biggest honor. That is recognition in itself. Our mission is accomplished if we can motivate people to form a group."

"And thus anyone is invited to be the honorary Haim sister."

Grammy Nod

The band are speaking from a break, where they're resting up after an lengthy tour in for their fourth album, I Quit.

They're currently 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 contention for the award.

"I watch the nominations every year, so it kind of feels like an out-of-body experience when your name is called," explains Alana. "I immediately called my sisters to say, 'Did I hear this correctly or am I hallucinating'?"

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

"We truly set out to make a guitar-driven album this time, so it's a huge milestone," adds Alana. "Yet we're just grateful for the female artists that inspired us."

Emotional Upheaval and Laughter

The record came out of a phase of emotional upheaval. All three sisters found themselves single, and the music explores that odd liminal space where you're happy to be free, but not yet ready to let go.

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

"I love way of putting it, yes," agrees Danielle. "I Quit is essentially a mantra. You have to actively work on shutting out the noise and saying, 'It doesn't matter to me what people think'."

Development of Music

That developed confidence called for a different sonic direction – more unpolished and powerful than any of the music the band had done before.

For Danielle, who co-produced the album, that began with the percussion.

"Percussion is such a specific thing, and I am so passionate about it," she states.

"'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 perfect drum sound."

Stories and Shared Laughter

The band's openness fueled the album's marketing, where the sisters revealed some of their romantic tales.

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

"When you're going through these heartbreaks, you just feel like there's no hope," explains Alana. "Thus to be able to find humor in those stories and hear others tell you even crazier stories, it's incredible."

A Confident Path

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

They're festival headliners, with successful albums and an global following.

Yet Haim will always be their primary priority.

"My sisters and I have been performing since I was little," concludes Alana. "There is no alternative that we were meant to do. And I'm really fortunate we've gotten here and we're still kicking."
