Haim celebrate their sister bond in new video for 'Hallelujah'

The stripped-down song was co-written by Tobias Jesso Jr. and produced by Ariel Rechtshaid, Rostam Batmanglij as well as Danielle Haim.

Although "Hallelujah" was described by Danielle Haim as about "about our bond as sisters," Alana Haim revealed that her verse pays homage to her late best friend, Sammi Kane Kraft, who died at the age of 20 in a car accident.

"I had always wanted to pay tribute to her in some way and I could never put how important she was into words. It felt like there were no words in the dictionary to encapsulate how special she was. Losing her put a lot of things into perspective for me. I was so lucky to have my sisters at this time in my life," she wrote in a lengthy note on Twitter.

In a separate post, Este Haim dedicated "Hallelujah" to anyone battling with chronic illness like herself.

The bassist, who was diagnosed with type 1 diabetes, explained that she began writing the song after receiving alarming news from her endocrinologist.

"I came home from the doctor super upset and frustrated and the only two people I felt comfortable enough to talk about it with were Danielle and Alana. Sometimes it feels like they're the only two people that truly understand me and support me when I feel like giving up," she wrote, also adding that the song is about the "people around us who we truly rely on for help and guidance."

"Hallelujah" was released along with a poignant video directed by Haim's frequent collaborator Paul Thomas Anderson, in which the three musicians further explore their sister bond.

"Give me direction when it is hard to fight/Three roads, one light/Now and then I can lean my back to yours/Travelin' like our feet don't touch the floor," Este and Danielle sing together, while sitting back-to-back in the air.

"Hallelujah" arrived on the heels of the new singles "Now I'm in It" and "Summer Girl," which will likely appear on the trio's forthcoming third studio album.

While their next studio opus is still in the works, Haim have recently covered Leonard Cohen's "If It Be Your Will" for the upcoming collaborative album, "Hanukkah+."

The record, due on November 22, will feature Hanukkah classics and originals recorded by some of the biggest names in the music industry, such as the Flaming Lips, Jack Black and Yo La Tengo.
