"Stonemilker" is a song recorded by Icelandic singer/songwriter Björk for her eighth studio album, "Vulnicura", in 2015.
 It was written and produced by Björk with beats by Venezuelan musician Arca.
 "Stonemilker" is "Vulnicura"' s opening track, and the first of a six-part narrative that details the devastating end of Björk's relationship to American contemporary artist Matthew Barney.
 Björk wrote the lyrics on the same Icelandic beach where the innovative 360-degree music video was later shot.
Irwin Lawrence "Paul" Mazursky (April 25, 1930 – June 30, 2014) was an American film director, screenwriter, and actor.
 Known for his dramatic comedies that often dealt with modern social issues, he was nominated for five Academy Awards: three times for Best Original Screenplay, once for Best Adapted Screenplay, and once for Best Picture for "An Unmarried Woman" (1978).
 Other films written and directed by Mazursky include "Bob & Carol & Ted & Alice" (1969), "Blume in Love" (1973), "Harry and Tonto" (1974), "Moscow on the Hudson" (1984), and "Down and Out in Beverly Hills" (1986).
Drawing Restraint 9 is a 2005 film project by visual artist Matthew Barney consisting of a feature-length film, large-scale sculptures, photographs, drawings, and books.
 The Drawing Restraint series consists of 19 numbered components and related materials.
 Some episodes are videos, others sculptural installations or drawings.
 Barney created "Drawing Restraint 1-6" while still an undergraduate at Yale University and completed "Drawing Restraint 16" in 2007 at London's Serpentine Gallery.
 With a soundtrack composed by Björk, "Drawing Restraint 9" is an unconventional love story set in Japan.
 The narrative structure is built upon themes such as the Shinto religion, the tea ceremony, the history of whaling, and the supplantation of blubber with refined petroleum for oil.
Matthew Barney (born March 25, 1967) is an American artist who works in sculpture, photography, drawing and film.
 His early works are sculptural installations combined with performance and video.
 Between 1994 and 2002 he created "The Cremaster Cycle", a series of five films described by Jonathan Jones in "The Guardian" as "one of the most imaginative and brilliant achievements in the history of avant-garde cinema."
 He is also known for "Drawing Restraint 9" (2005), as well as his past relationship with Icelandic singer Björk.
Matthew Barney: No Restraint is a 2006 documentary directed by Alison Chernick.
 It follows artist Matthew Barney (best known for "The Cremaster Cycle") and his collaborator, singer-songwriter Björk, as they embark on a filmmaking journey in Japan.
 It reveals Barney's process in creating Drawing Restraint 9, a cinematic "piece" that combines a whaling vessel; 45,000 pounds of petroleum jelly; and traditional Japanese rituals into a fantasy love story.
Bob & Carol & Ted & Alice is a 1969 American comedy drama film directed by Paul Mazursky, written by Paul Mazursky and Larry Tucker, who also produced the film, and starring Natalie Wood, Robert Culp, Elliott Gould, and Dyan Cannon.
 The original music score was composed by Quincy Jones, and featured Jackie DeShannon performing Burt Bacharach and Hal David's "What the World Needs Now Is Love" and Sarah Vaughan performing "I know that my Redeemer liveth" from Part III of Handel's "Messiah".
 The cinematography for the film was by Charles Lang.
 The film received four Academy Award nominations, including ones for Gould and Cannon.

Alex in Wonderland is a 1970 American comedy-drama film directed by Paul Mazursky, written with his partner Larry Tucker, starring Donald Sutherland and Ellen Burstyn.
 Sutherland plays Alex Morrison, a director agonizing over the choice of follow-up project after the success of his first feature film.
 The situation is similar to the one Mazursky found himself in following the success of "Bob & Carol & Ted & Alice" (1969) and he casts himself in a role as a new-style Hollywood producer.
 His daughter Meg Mazursky appears as Amy, one of Morrison's daughters.
 Noted teacher of improvisational theater Viola Spolin plays Morrison's mother.
 The film also features cameo appearances by Federico Fellini and Jeanne Moreau, and seems to be inspired by their work.
 In particular, Fellini's "8½" (1963), about a film director who's artistically stuck, is referenced.
 Moreau sings two songs on the soundtrack, "Le Vrai Scandale" (for which she wrote the words) and "Le Reve Est La."
The Music from Matthew Barney's Drawing Restraint 9 is a soundtrack created by Björk in collaboration with her then-partner Matthew Barney for his film of the same title.
 For this project Björk traveled to Japan to study ancient Japanese music.
 Several tracks are made with the sound of the shō, a Japanese instrument which contains 16 various reeds; the shō performances are from Mayumi Miyata, one of the world's greatest shō players.
 She also appears in the film, playing her instrument.
 The song "Holographic Entrypoint" features a Noh score and vocal performance by Shiro Nomura.
 Björk brought "Nameless" back from her 2003 tour, and, with the help of Leila Arab, looped and edited it to create the track "Storm".

 "Gratitude", "Shimenawa" and "Cetacea" feature harp player Zeena Parkins, who previously collaborated with Björk on her 2001 album "Vespertine".

 The track "Storm" was featured in the 2012 video game "".
