"When are you chatting with Haim?" a message pops up. "I was hoping to ask if I can become their fourth member."
However, there remains a single issue: The sender also wants to be the Haims' additional sibling. And we're in plentiful company. Several famous supporters have publicly petitioned for the role.
One thing is obvious a special quality is at play. The siblings Este, Danielle and Alana launched their career doing sets at local delicatessens with their parents. Presently, they stand as multi-time Grammy Award nominees.
Similar to the most iconic groups, they're a inseparable trio. Their videos frequently depict them striding in unison down the streets of Los Angeles. On stage, they play with such unfettered exuberance you inevitably think, "I wish to be a piece of that, too."
"How often on tour that fans approached us and said, 'Watching you live, I bought a drum kit'," states Alana, the most junior of the Haim siblings. "That's the biggest honour. It is a prize in itself. We have succeeded if we can inspire others to make music."
"And thus anyone gets an invitation to be the fourth Haim sister."
The band are speaking from a break, where they're recovering after an lengthy tour in promoting their new album, I Quit.
They're presently celebrating the news it's been shortlisted for Best Rock Album at the Grammys – with Haim the very first all-female band ever in the running for the award.
"I watch the lists every year, so it almost feels like an out-of-body experience when your name is read out," says Alana. "I immediately called my sisters to say, 'Did I hear this right or am I hallucinating'?"
The importance of the nomination isn't lost on the sisters.
"We truly set out to make a rock record this time, so it's a major milestone," continues Alana. "However we're just appreciative for the female artists that came before us."
The album emerged from a time of personal change. All three sisters ended up single, and the music explores that strange liminal space where you're glad to be free, but not yet ready to move on.
The themes detail departures and partings. The sisters desire love, but not the specific love they've experienced. You can hear them working out in real time who they are becoming.
"I love description, yes," says Danielle. "I Quit is kind of like a slogan. You have to consciously practice ignoring the outside opinions and saying, 'I couldn't care less what people think'."
That newfound confidence demanded a fresh approach – more raw and powerful than anything the band had done before.
For Danielle, who co-produced the album, that started with the percussion.
"Percussion is such a specific thing, and I care so much about it," she emphasizes.
"'Journey of the drum sound' will be the subject of our biography," jokes Alana. "I always say, our albums cannot begin until we find the ideal drum sound."
The trio's candor shaped the album's marketing, where the sisters revealed some of their romantic horror stories.
Someone ended things with Este over a medical concern. Alana shared a story of travelling to celebrate New Year's Eve with someone, only to receive a casual gesture at midnight.
"During these breakups, you just feel like there's only darkness," says Alana. "So to be able to laugh at those stories and hear others tell you wilder stories, it's incredible."
One can easily sense a evolution in the band. These days, Haim are more confident of their position in the music world.
They're festival headliners, with chart-topping albums and an worldwide audience.
However Haim will consistently be their primary priority.
"We have been playing music since I was a young child," says Alana. "There is no other path that we were meant to do. And I'm really fortunate we've made it and we're still kicking."
