Context paragraphs:
Wah Wah (album): Wah Wah is the sixth studio album by the Manchester-based English indie rock band James.  After the success of their fourth album, "Seven" (1992), the band entered Real World Studios, Box, Wiltshire, to record their fifth album "Laid" in early 1993 with producer Brian Eno, who the group had longed to work with.  Prior to recording "Laid", Eno observed the band's jam sessions at their Manchester rehearsal room, and considered these improvised pieces to be as important to the band's music as their eventually crafted songs.  He requested to the group that whilst they were recording "Laid", they would also concurrently record an album of their improvisations which Eno and, by Eno's request, second producer Markus Dravs would produce in a secondary studio in the Real World complex.  Each composition started off with the band's improvisation being recorded, which Dravs would then edit, generally alone whilst James and Eno were recording "Laid".  Eno and Dravs would take a "promising" part of a recording and then mixed them only once.  Tim Booth's desire to re-record some of his vocals caused friction in the studio.

Taking Tiger Mountain by Strategy (film): Taking Tiger Mountain by Strategy () is a Chinese film from 1970, during the height of the Cultural Revolution.  The film was directed by Xie Tieli and was based on a contemporary Beijing opera, one of the eight model plays allowed during the Cultural Revolution.  The story is based on the novel "Lin hai xue yuan" (林海雪原), and tells the story of an incident in 1946, during the Chinese Civil War.

Here Come the Warm Jets: Here Come the Warm Jets is the debut solo album by Brian Eno, credited only as "Eno".  Produced by him, it was released on Island Records in January 1974.  The musical style of "Here Come the Warm Jets" is a hybrid of glam rock and art pop, similar to Eno's previous album work with Roxy Music, although in a stronger experimental fashion.  In developing the album's words and music, Eno used unusual methods such as dancing for his band members and having them play accordingly, and singing nonsense words to himself that would form the basis of subsequent lyrics.  The album features various guest musicians, including members of Roxy Music, Hawkwind, Matching Mole and Pink Fairies, as well as Chris Spedding, and Robert Fripp of King Crimson, who collaborated with Eno a year before in "(No Pussyfooting)".

Taking Tiger Mountain (By Strategy): Taking Tiger Mountain (By Strategy) is the second solo album by English musician Brian Eno.  Produced by Eno, it was originally released by Island Records in November 1974.  Unlike his previous album "Here Come the Warm Jets", Eno used a core band of five instrumentalists (keyboards, guitars, bass, drums and percussion) and used fewer guest musicians.  Also participating was guitarist and co-writer Phil Manzanera, who had played with Eno in Roxy Music.  To help guide the production of the album, Eno and Peter Schmidt developed instruction cards called Oblique Strategies to use through the creative process of the album.

Mykonos (song): Mykonos is the third single from indie folk band Fleet Foxes, from their 2008 EP "Sun Giant".

On May 5, 2009, it was released in the U.S. on Seattle-based record label Sub Pop, with the song "False Knight On the Road" in place of "Tiger Mountain Peasant Song".  An alternate version of the song, with a track length of 3:39, was released on the deluxe version of their debut album "Fleet Foxes".

Taking Tiger Mountain by Strategy: Taking Tiger Mountain by Strategy (Chinese: 智取威虎山; pinyin: zhì qǔ wēi hǔshān) is a Peking opera, and one of the eight model plays allowed during the Chinese Cultural Revolution.  The story is based on the novel "Lin hai xue yuan" (林海雪原) by Qu Bo, which in turn, is based on the real-life story of an incident in 1946 during the Chinese Civil War, involving a communist reconnaissance team soldier Yang Zirong (杨子荣) who disguised himself as a bandit to infiltrate a local gang of bandits, eventually helping the main communist force to destroy the bandits.  Unlike other characters depicted in the opera and novel, most of the names of both the protagonists and the bandits are real.

Peter Schmidt (artist): Peter Schmidt (17 May 1931 – 22 January 1980) was a Berlin-born British artist, painter, theoretician of color and composition, pioneering multimedia exhibitor and an influential teacher at Watford College of Art.  He was part of a generation of art school teachers in the 1960s and 1970s that had great impact on some students who later went on to work in art and music.  He worked with Hansjörg Mayer, Brian Eno, Mark Boyle, Dieter Roth and had associations with Russell Mills, David Toop and Tom Phillips.

Discreet Music: Discreet Music (1975) is the fourth studio album by the British musician Brian Eno.  While his earlier work with Robert Fripp on "(No Pussyfooting)" and several selections from "Another Green World" feature similar ideas, "Discreet Music" marked a clear step toward the ambient aesthetic Eno would later codify with 1978's "".  It is also Eno's first album to be released under his full name "Brian Eno" as opposed to his previous rock albums released simply under the name "Eno".
