Everyone is Encouraged to Become the Fourth Haim Sisters Sister.

"Do you know when you'll be speaking to the Haim sisters?" an inquiry arrives. "I wanted to ask if I can be their fourth member."

There's just a key snag: The sender also longs to be the Haims' newest recruit. What's more, we are far from alone. A host of celebrated fans have publicly begged for the position.

It's clear something is at play. The siblings Este, Danielle and Alana launched their musical journey performing shows at local delicatessens with their parents. Today, they are repeated Grammy Award hopefuls.

In the tradition of the most iconic bands, they're a tight-knit trio. Their visuals often feature them striding in sync down the avenues of Los Angeles. On stage, they perform with such unfettered happiness you find yourself thinking, "I wish to be involved in that, too."

"The amount of times on tour that audience members told us and said, 'After your show, I picked up a drum kit'," says Alana, the most junior of the Haim siblings. "That's the ultimate honour. It is a prize in itself. We have succeeded if we can inspire others to form a group."

"And thus anyone are welcome to be the fourth Haim sister."

Grammy Nod

The trio have called into their homes, where they're recovering after an extensive tour in support of their new album, I Quit.

They're currently reeling from the news it's been in the running for best rock album at the Grammys – with Haim the pioneering all-female band ever in the running for the trophy.

"I tune into the nominations every year, so it sort of feels like a surreal movie when your name is called," says Alana. "I needed to phone my sisters to say, 'Did we just hear this right or am I dreaming'?"

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

"We deliberately set out to make a rock record this time, so it's a huge achievement," continues Alana. "However we're just thankful for the women that paved the way."

Emotional Upheaval and Candor

The record emerged from a period of emotional upheaval. All three sisters ended up single, and the music explores that unique liminal space where you're happy to be free, but not quite ready to start anew.

The words detail breakups and goodbyes. The sisters desire love, but not the specific love they've got. You can hear them figuring out in real life 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'."

Development of Sound

That recent resilience demanded a new sound – more unpolished and powerful than any of the music the band had done before.

For Danielle, who helped produce the album, that started with the percussion.

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

"'Journey of the drum sound' will be the subject of our book," laughs Alana. "Our motto is, our albums cannot begin until we find the right drum sound."

Experiences and Collective Laughter

The band's candor shaped the album's promotional campaign, where the sisters disclosed some of their romantic tales.

A former partner ended things with Este over a medical consideration. Alana told a story of flying to spend New Year's Eve with someone, only to receive a casual gesture at midnight.

"Experiencing these setbacks, you just feel like there's no hope," says Alana. "So to be able to laugh at those stories and hear others tell you more outrageous stories, it's so amazing."

An Assured Future

It's not difficult sense a change in the band. Today, Haim are more confident of their position in the music world.

They're major draws, with successful albums and an international fan base.

But the band will consistently be their top commitment.

"Me and my siblings have been making music since I was a young child," says Alana. "There is nothing else that we were destined for. And I'm really grateful we've gotten here and we're still kicking."
