Everyone is Encouraged to Be the Fourth Haim Sisters Sister.

"Do you know when you'll be chatting with Haim?" a message reads. "I was hoping to ask if I can join as their extra sister."

However, there remains a single issue: The author likewise desires to be Haim's additional sibling. And we're far from alone. A host of high-profile admirers have also coveted the honor.

One thing is obvious an irresistible appeal is going on. Sisters Este, Danielle and Alana began their career doing sets at local delicatessens with their parents. Now they're repeated Grammy Award nominees.

In the tradition of the best bands, they're a tight-knit unit. Their music videos often feature them striding in unison down the avenues of Los Angeles. During performances, they play with such boundless exuberance you can't help but think, "I'd love to be involved in that, too."

"How often on tour that fans came up to us and said, 'Watching you live, I got a drum kit'," says Alana, the most junior of the trio. "That's the ultimate compliment. That is recognition in itself. We have succeeded if we can encourage young girls to make music."

"So all gets an invitation to be the fourth member of Haim."

Grammy Milestone

The trio are speaking from a break, where they're recovering after an lengthy tour in for their latest 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 female band ever in contention for the award.

"I watch the lists every year, so it sort of feels like an out-of-body experience when your name is announced," explains Alana. "I had to call my sisters to say, 'Did I hear this correctly or am I dreaming'?"

The importance of the honor is deeply felt by the trio.

"We really set out to make a rock album this time, so it's a significant step," says Alana. "However we're just appreciative for the women that came before us."

Heartbreak and Laughter

The album was born from a phase of transition. All three sisters were single, and the music captures that unique transitional period where you're happy to be free, but not entirely ready to start anew.

The themes follow endings and partings. The sisters seek love, but not the relationships they've got. You can hear them figuring out in real life who they want to be.

"That's a perfect summary, yes," agrees Danielle. "I Quit is essentially a slogan. You have to actively work on ignoring the outside opinions and saying, 'It doesn't matter to me what people think'."

Evolution of Sound

That recent toughness demanded a different sonic direction – more organic and immediate than any of the music the band had done before.

For Danielle, who helped produce the album, that began with the drum sound.

"Percussion is such a detailed thing, and I focus so intensely about it," she emphasizes.

"'Journey of the drum sound' will be the title of our book," jokes Alana. "I always say, our albums won't commence until we find the right drum sound."

Experiences and Shared Laughter

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

A former partner ended things with Este over a medical concern. Alana recalled a story of flying to celebrate New Year's Eve with someone, only to receive a friendly slap at midnight.

"Experiencing these heartbreaks, you just feel like there's no hope," notes Alana. "Therefore to be able to share those stories and have them tell you more outrageous stories, it's incredible."

An Assured Path

One can easily sense a change in the band. These days, Haim are more certain of their place in the rock pantheon.

They're festival headliners, with hit albums and an international audience.

Yet Haim will forever be their top focus.

"We have been making music since I was a young child," shares Alana. "It's like no other path that we were supposed to do. And I'm really thankful we've gotten here and we're still making music."
