The World is Invited to Become the Extra Haim Sisters Member.

"Any idea when you're chatting with the Haim sisters?" a text reads. "I wanted to ask if I can join as their extra sister."

However, there remains a key snag: The author likewise desires to be the Haims' newest recruit. Furthermore, we are far from alone. A host of famous supporters have publicly coveted the role.

It's clear a special quality is happening. The siblings Este, Danielle and Alana began their musical journey playing gigs at neighborhood delis with their family. Now they're multi-time Grammy Award contenders.

Similar to the best ensembles, they're a inseparable trio. Their music videos repeatedly show them walking in sync down the streets of Los Angeles. During performances, they jam with such pure happiness you find yourself thinking, "I want to be part of that, too."

"How often on tour that audience members told us and said, 'Watching you live, I picked up a bass'," states Alana, the most junior of the trio. "That's the greatest honour. That is recognition in itself. We've done our job if we can motivate young girls to make music."

"Therefore anyone gets an invitation to be the next member of Haim."

Award Nod

The band have called into home, where they're recovering after an extensive tour in support of their fourth album, I Quit.

They're right now reeling from the news it's been in the running for Best Rock Album at the Grammys – with Haim the first all-woman band ever in the running for the award.

"I watch the announcements every year, so it almost feels like an out-of-body experience when your name is read out," says Alana. "I needed to phone my sisters to say, 'Did we just hear this correctly or am I hallucinating'?"

The significance of the honor isn't lost on the trio.

"We truly set out to make a guitar-driven album this time, so it's a huge step," says Alana. "But we're just appreciative for the female artists that came before us."

Heartbreak and Humour

The record was born from a time of personal change. All three sisters found themselves single, and the music explores that strange in-between place where you're happy to be free, but not entirely ready to start anew.

The themes follow breakups and farewells. The sisters want love, but not the specific love they've got. You can hear them determining in real life who they are becoming.

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

Evolution of Music

That developed confidence called for 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.

"Drums are such a specific thing, and I am so passionate about it," she says.

"'Journey of the drum sound' will be the name of our book," jokes Alana. "Our motto is, our albums don't start until we find the ideal drum sound."

Experiences and Shared Humor

The trio's candor fueled the album's marketing, where the sisters disclosed some of their personal tales.

A former partner broke up with Este over a medical concern. Alana told a story of flying 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 only darkness," says Alana. "Thus to be able to laugh at those stories and hear others tell you wilder stories, it's incredible."

A Secure Path

It's not difficult sense a evolution in the band. Now, Haim are more assured of their position in the music world.

They're top-billed acts, with hit albums and an global fan base.

Yet the sister act will forever be their number one commitment.

"My sisters and I have been making music since I was little," shares Alana. "It's like nothing else that we were supposed to do. And I'm really thankful we've made it and we're still kicking."
