Context paragraphs:
Stutter (Elastica song): "Stutter" is a song by the Britpop group Elastica and was written by lead singer Justine Frischmann.  It was originally released as a single in 1993 and then included on the band's 1995 self-titled debut album.  The single, which received positive reviews from critics, charted in the US and Canada.

Chuck Schuldiner: Charles Michael Schuldiner (May 13, 1967 – December 13, 2001) was an American singer, songwriter, and guitarist.  He founded the pioneering band Death in 1983.  Schuldiner is often referred to as "The Godfather of Death metal",

Death (metal band): Death was an American death metal band from Orlando, Florida, founded in 1983 by guitarist and vocalist Chuck Schuldiner.  Death is considered to be one of the most influential bands in heavy metal and a pioneering force in death metal.  Its debut album, "Scream Bloody Gore", has been widely regarded as the first death metal record, while the band's driving force, Chuck Schuldiner, is acknowledged as the originator of extreme metal.  Death had a revolving lineup, with Schuldiner being the sole consistent member.  The group's style also progressed, from the raw sound on its early albums to a more sophisticated one in its later stage.  The band ceased to exist after Schuldiner died of glioma and pneumonia in December 2001, but remains an enduring metal band.

Suede discography: The discography of the English alternative rock band Suede consists of seven studio albums, three compilation albums, five video albums and over twenty singles. Suede were formed in 1989 by singer Brett Anderson, bassist Mat Osman and guitarist Justine Frischmann.  Guitarist Bernard Butler later joined after the group responded to an ad in the "Melody Maker".  The group played as a four-piece with a drum machine until drummer Simon Gilbert joined.  Frischmann left before the group released any material.

Love and Poison (book): Love and Poison is the official biography of the English alternative rock band Suede.  The book, written by long-time band associate David Barnett, reveals the real stories behind singer Brett Anderson's battle with drugs, his relationship with Elastica's Justine Frischmann and the subsequent feud with Blur after she started stepping out with Damon Albarn.

M.I.A. discography: English singer, songwriter and rapper M.I.A. has released five studio albums, two extended plays, two mixtapes, thirty-three singles (including six as a featured artist) and twenty-seven music videos. Born Mathangi "Maya" Arulpragasam, M.I.A. began her career as a visual artist and film-maker, and moved into making music after filming a documentary on the band Elastica in 2001.  The band's lead singer, Justine Frischmann, lent her a Roland MC-505 sequencer/drum machine which she used to make a demo tape that secured her a contract with British label XL Recordings.

Justine Frischmann: Justine Elinor Frischmann (born 16 September 1969) is an English artist and former musician, best known for being the lead singer of the Britpop band Elastica.  She is now pursuing a career as a painter.

Pleasure (Norwegian band): Pleasure is a Norwegian funky pop band, led by Fred Ball.  One single was released in 2003, "Don't Look The Other Way", which featured Justine Frischmann (former lead singer for Elastica) on vocals.

Elastica 6 Track EP: When released in 1999, Elastica's 6 Track EP was the first new material issued by the band since their self-titled debut four years earlier.  According to bandleader Justine Frischmann the EP represented more of a document of what the band was up to during the interim rather than a return to form: "The material has been chosen to allow people to hear rarities and demos which reflect all stages of the bands recording between 1996 and 1999.  The EP is certainly not intended to be some big comeback record."  Indeed, several of the songs would later find themselves on their second album "The Menace" (2000) although in more polished form.

Galang (song): "Galang" is a song by British musician M.I.A. from her debut album "Arular".  It was released on Showbiz Records in 2003 as her first single, which pressed 500 vinyl copies, gaining immediate international recognition via radio airplay, fashion shows, club rotations and internet filesharing.  "Galang" was re-released on 1 November 2004 via XL Recordings as the second single from the album released by the label and was released for a third time as "Galang '05" on 11 October 2005 by the label and in the US by Interscope Records.  It is written by Maya "M.I.A." Arulpragasam, Justine Frischmann, Ross Orton and Steve Mackey.  It first appeared on M.I.A.'s six song demo tape in 2003, her official MySpace account on 9 June 2004 and was later reworked slightly by Orton and Mackey who received production credit for the song.  "Galang" was the second song M.I.A. wrote on her Roland MC-505, intending for the piece to be performed by Frischmann's band Elastica.  Inspired by her experiences and observations of life in London, M.I.A. wrote the song to encourage her friends in the band to continue to make music.  However, after cowriting the song, Frischmann convinced M.I.A. to record "Galang" herself, complimenting the piece's lyrical narrative and music direction.
