The World Are Welcome to Join as the Extra Haim Sisters Bandmate.

"Any idea when you're chatting with Haim?" a message reads. "I was hoping to ask if I can become their fourth member."

There is only one problem: The sender also wants to be the Haims' additional sibling. Furthermore, we are in plentiful company. Multiple high-profile fans have openly petitioned for the honor.

The evidence suggests a special quality is at play. Sisters Este, Danielle and Alana started their career playing gigs at neighborhood delis with their family. Today, they are repeated Grammy Award nominees.

In the tradition of the greatest groups, they're a inseparable unit. Their visuals frequently feature them marching in harmony down the streets of Los Angeles. On stage, they play with such pure happiness you find yourself thinking, "I'd love to be part of that, too."

"The numerous instances on tour that young girls approached us and said, 'After your show, I got a drum kit'," states Alana, the most junior of the Haim siblings. "That's the biggest honour. That is recognition in itself. Our mission is accomplished if we can encourage others to form a group."

"Therefore everyone are welcome to be the fourth part of the family."

Award Milestone

The trio have called into home, where they're taking a pause after an major tour in for their latest album, I Quit.

They're right now reeling from the news it's been shortlisted for best rock album at the Grammys – with Haim the very first female band ever in contention for the trophy.

"I follow the lists every year, so it kind of feels like a surreal movie when your name is called," says Alana. "I immediately called my sisters to say, 'Am I hearing this correctly or am I imagining things'?"

The importance of the accolade isn't lost on the sisters.

"We deliberately set out to make a rock record this time, so it's a major milestone," says Alana. "Yet we're just appreciative for the pioneers that inspired us."

Personal Turmoil and Humour

The album emerged from a period of emotional upheaval. All three sisters found themselves single, and the music explores that odd transitional period where you're glad to be free, but not entirely ready to move on.

The themes track breakups and goodbyes. The sisters want love, but not the kind of love they've got. You can hear them figuring out in real life who they want to be.

"That's a perfect way of putting it, yes," agrees Danielle. "I Quit is essentially a personal statement. You have to make an effort in shutting out the noise and saying, 'I couldn't care less what people think'."

Refinement of Style

That newfound confidence required a fresh approach – more unpolished 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 nuanced thing, and I focus so intensely about it," she states.

"'Journey of the drum sound' will be the subject of our book," quips Alana. "I've said it, our albums won't commence until we find the ideal drum sound."

Experiences and Shared Camaraderie

The trio's openness inspired the album's rollout, where the sisters shared some of their romantic horror stories.

A former partner broke up with Este over a health concern. Alana shared a story of flying to celebrate New Year's Eve with someone, only to receive a casual gesture at midnight.

"When you're going through these breakups, you just feel like there's only darkness," explains Alana. "Thus to be able to laugh at those stories and hear others tell you wilder stories, it's incredible."

An Assured Path

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

They're festival headliners, with chart-topping albums and an worldwide fan base.

But Haim will consistently be their primary commitment.

"Me and my siblings have been making music since I was little," concludes Alana. "It feels as if nothing else that we were supposed to do. And I'm really fortunate we've made it and we're still going strong."
