The World is Invited to Join as the Extra Haim Member.

"When are you interviewing the band?" a message arrives. "I was hoping to ask if I can be their fourth member."

However, there remains a single issue: The author likewise longs to be Haim's newest recruit. And we're not alone. Multiple high-profile admirers have openly coveted the role.

It's clear an irresistible appeal is happening. Sisters Este, Danielle and Alana launched their musical journey performing shows at local delicatessens with their family. Today, they are multi-time Grammy contenders.

Similar to the greatest bands, they're a tight-knit gang. Their videos repeatedly depict them walking in harmony down the streets of Los Angeles. On stage, they jam with such pure exuberance you find yourself thinking, "I want to be part of that, too."

"The numerous instances on tour that fans told us and said, 'Watching you live, I bought a bass'," remarks Alana, the youngest of the sisters. "That is the ultimate compliment. It is a prize in itself. Our mission is accomplished if we can encourage people to start a band."

"So all are welcome to be the fourth part of the family."

Grammy Milestone

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

They're presently celebrating the news it's been shortlisted for best rock album at the Grammy Awards – with Haim the first all-female band ever in contention for the prize.

"I watch the lists every year, so it kind of feels like a surreal movie when your name is announced," notes Alana. "I immediately called my sisters to say, 'Am I hearing this right or am I dreaming'?"

The importance of the accolade resonates with the band.

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

Personal Turmoil and Laughter

The record came out of a period of personal change. All three sisters found themselves single, and the music explores that strange transitional period where you're relieved to be free, but not entirely ready to move on.

The words track endings and goodbyes. The sisters desire love, but not the kind of love they've experienced. You can hear them working out in real life who they aspire to be.

"That's a perfect way of putting it, yes," responds Danielle. "I Quit is essentially a mantra. You have to make an effort in shutting out the noise and saying, 'I don't give what people think'."

Refinement of Sound

That newfound confidence required a fresh approach – more unpolished and direct than any of the music the band had done before.

For Danielle, who co-produced the album, that was founded on the drums.

"Drums are such a specific thing, and I focus so intensely about it," she states.

"'Journey of the drum sound' will be the name of our memoir," laughs Alana. "I've said it, our albums don't start until we find the right drum sound."

Anecdotes and Shared Camaraderie

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

One man left Este over a health consideration. Alana recalled a story of travelling to celebrate New Year's Eve with someone, only to receive a high five at midnight.

"During these breakups, you just feel like there's no hope," explains Alana. "Thus to be able to find humor in those stories and have them tell you more outrageous stories, it's incredible."

An Assured Legacy

It's not difficult sense a evolution in the band. Today, Haim are more confident of their place in the rock pantheon.

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

But Haim will always be their top commitment.

"My sisters and I have been performing since I was little," shares Alana. "It's like no other path that we were meant to do. And I'm really thankful we've reached this point and we're still going strong."
