The World is Encouraged to Become the Extra Haim Member.

"When are you speaking to the Haim sisters?" an inquiry reads. "I wanted to ask if I can be their fourth member."

However, there remains a key snag: The sender also wants to be Haim's newest recruit. And we're far from alone. A host of famous supporters have also begged for the role.

It's clear an irresistible appeal is going on. Sisters Este, Danielle and Alana launched their career playing gigs at local delicatessens with their family. Now they're repeated Grammy Award nominees.

Like all the most iconic groups, they're a inseparable unit. Their visuals frequently depict them marching in unison down the roads of Los Angeles. During performances, they perform with such unfettered exuberance you find yourself thinking, "I wish to be involved in that, too."

"The numerous instances on tour that audience members approached us and said, 'After your show, I bought a bass'," states Alana, the most junior of the trio. "That is the greatest compliment. It is a prize in itself. We've done our job if we can inspire others to start a band."

"So everyone gets an invitation to be the next Haim sister."

Grammy Nod

The trio are connecting from their homes, where they're recovering after an lengthy tour in support of their new album, I Quit.

They're presently reeling from the news it's been in the running for best rock album at the Grammy Awards – with Haim the pioneering all-woman band ever in the running for the prize.

"I follow the lists every year, so it sort of feels like an out-of-body experience when your name is announced," says Alana. "I immediately called my sisters to say, 'Did we just hear this right or am I hallucinating'?"

The importance of the nomination resonates with the sisters.

"We deliberately set out to make a guitar-driven album this time, so it's a major achievement," adds Alana. "However we're just grateful for the pioneers that inspired us."

Emotional Upheaval and Humour

The project came out of a period of personal change. All three sisters were single, and the music explores that strange liminal space where you're happy to be free, but not entirely ready to let go.

The themes detail departures and farewells. The sisters want love, but not the kind of love they've got. You can hear them determining in real time who they are becoming.

"I love description, yes," responds Danielle. "I Quit is kind of like a personal statement. You have to make an effort in blocking the outside opinions and saying, 'I don't give what people think'."

Evolution of Sound

That newfound resilience demanded a fresh approach – more raw and immediate than anything the band had done before.

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

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

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

Anecdotes and Shared Humor

The trio's candor shaped the album's rollout, where the sisters shared some of their romantic misadventures.

One man ended things with Este over a medical concern. Alana told a story of travelling to spend New Year's Eve with someone, only to receive a casual gesture at midnight.

"During these heartbreaks, you just feel like there's only darkness," says Alana. "Therefore to be able to find humor in those stories and have them tell you even crazier stories, it's therapeutic."

An Assured Legacy

You can clearly sense a evolution in the band. These days, Haim are more assured of their position in the music world.

They're top-billed acts, with hit albums and an worldwide audience.

However the band will always be their primary focus.

"Me and my siblings have been playing music since I was a young child," says Alana. "It's like no alternative that we were meant to do. And I'm really fortunate we've reached this point and we're still going strong."
