[4] Although Robertson did not want to compose "any stereotypical Indian music" for the soundtrack,[5] his heritage and experiences helped him incorporate tribal elements into the blues rock sound of the album.

[13] During principal photography, Robertson visited the film set in Oklahoma to meet with Osage musicians and ensure the authenticity of his music.

[16] Despite Robertson's progressing prostate cancer, he was able to complete the score and attend a private album release party before he passed away in August 2023.

"[20] Scorsese and actors Leonardo DiCaprio and Lily Gladstone had attended the Osage Nation's annual I'n-Lon-Schka dances in June 2021.

"[19] Brian Tallerico of Roger Ebert wrote that "Robbie Robertson's thrumming score is practically a character, giving the film a heartbeat that adds tension to its notable runtime.

[24] Hamish MacBain of the Evening Standard wrote that Robertson's score was "absolutely fantastic, particularly the recurring, minimal, two note retro-bass motif that effectively ramps up the tension at key points.

[27] Tim Greiving of the Los Angeles Times wrote that "Robertson's contribution is an astonishing and lively musical ecosystem that gives immediate authenticity to Scorsese's equally vivid presentation of Osage life and culture in 1920s Oklahoma.

It's music that proudly worships and dances with these people — and alternately weeps for their oppression, at times sounding almost sick at their treatment by the story's white predators."

"[1] On November 15, 2023, Martin Scorsese held a tribute concert for Robertson, which included excerpts from his Killers of the Flower Moon score.
