Question: What American transgender actress starred in Andy Warhol's films and was a muse of the protopunk band The Velvet Underground, a rock band formed what year in New York City?
Context: "Femme Fatale" is a song by The Velvet Underground from their 1967 debut album "The Velvet Underground & Nico", with lead vocals by Nico.  At producer Andy Warhol's request, band frontman Lou Reed wrote the song about Warhol superstar Edie Sedgwick.  The song was released as a B-Side to "Sunday Morning" in December 1966.  It is one of the gentler songs of the album, coming as a direct contrast to the preceding, abrasive song, "I'm Waiting for the Man". "If You Were Still Around" is a song by Welsh musician and composer John Cale.  It was written by John Cale together with playwright Sam Shepard.  It was originally released on Cale's 1982 album "Music for a New Society".  On 27 October 2014, a year after the death of his The Velvet Underground–bandmate Lou Reed, Cale released a new version of this song.  For this version was also released music video directed by Abigail Portner.  At the beginning of the video Cale is lying on the floor in a fetal position and after he views the photos of Reed and other deceased people associated with the Velvet Underground and The Factory: Sterling Morrison, Nico, Andy Warhol, and Edie Sedgwick. Eat/Kiss: Music for the Films by Andy Warhol is a soundtrack album by Welsh multi-instrumentalist and composer John Cale.  It was released in 1997 on Hannibal Records.  Cale composed this music for a screening of two Andy Warhol films, "Eat" and "Kiss".  It was premiered in 1994 with two other The Velvet Underground members, guitarist Sterling Morrison and drummer Maureen Tucker.  An album version was recorded next year without Morrison in Lille, France. The Exploding Plastic Inevitable, sometimes simply called Plastic Inevitable or EPI, was a series of multimedia events organized by Andy Warhol between 1966 and 1967, featuring musical performances by The Velvet Underground and Nico, screenings of Warhol's films, and dancing and performances by regulars of Warhol's Factory, especially Mary Woronov and Gerard Malanga.  "Andy Warhol's Exploding Plastic Inevitable" is also the title of an 18-minute film by Ronald Nameth with recordings from one week of performances of the shows which were filmed in Chicago, Illinois, in 1966.  In December 1966 Warhol included a one-off magazine called "The Plastic Exploding Inevitable" as part of the "Aspen" No. 3 package. Empire is a 1964 American black and white silent film written, produced, and directed by Andy Warhol.  It consists of eight hours and five minutes of continuous slow motion footage of the Empire State Building in New York City.  Abridged showings of the film were never allowed, and supposedly the unwatchability of the film was an important part of the reason the film was created.  However, a legitimate Italian VHS produced in association with the Andy Warhol Museum in 2000 contains only an extract of 60 minutes.  Its use of the long take "in extremis" is an extension of Warhol's earlier work the previous year with "Sleep".  Warhol employed Rob Trains to be the projectionist for a screening of the film.  Trains miscalculated and mixed the order and speed of the reels for the eight-hour movie.  After a positive review in "The New York Times", Warhol actually liked the "mistake" and employed Trains for the entire summer. Candy Darling (November 24, 1944 – March 21, 1974) was an American transgender actress, best known as a Warhol Superstar.  She starred in Andy Warhol's films "Flesh" (1968) and "Women in Revolt" (1971), and was a muse of the protopunk band The Velvet Underground. The Velvet Underground was a rock band formed in 1964 in New York City by singer/guitarist Lou Reed, multi-instrumentalist John Cale, guitarist Sterling Morrison, and drummer Angus MacLise (replaced by Moe Tucker in 1965).  The group's integration of rock and the avant-garde achieved little commercial success during their existence, but they are now recognized as one of the most influential bands in rock, underground, experimental, and alternative music.  The provocative subject matter, musical experimentation, and often nihilistic attitudes explored in the band's work would prove influential in the development of punk rock and new wave music. I Shot Andy Warhol is a 1996 American-British independent film about the life of Valerie Solanas and her relationship with the artist Andy Warhol.  The film marked the debut of Canadian director Mary Harron.  The film stars Lili Taylor as Valerie, Jared Harris as Andy Warhol, and Martha Plimpton as Valerie's friend Stevie.  Stephen Dorff plays Warhol superstar Candy Darling.  John Cale of The Velvet Underground wrote the film's score despite protests from former band member Lou Reed.  Yo La Tengo plays an anonymous band that is somewhat reminiscent of the group. The Velvet Underground & Nico is the debut album by American rock band the Velvet Underground, released in March 1967 by Verve Records.  Accompanied by vocalist Nico, the album was recorded in 1966 while the group were featured on Andy Warhol's Exploding Plastic Inevitable multimedia event tour, which gained attention for its experimental performance sensibilities and controversial lyrical topics, including drug abuse, prostitution, sadomasochism and sexual deviancy. The Complete Matrix Tapes is a live album by the New York City-based experimental rock band the Velvet Underground, released on November 20, 2015.  It features unexpurgated recordings of the band's two-night stint on November 26 and 27, 1969, at San Francisco club The Matrix, owned and operated by Jefferson Airplane's Marty Balin.  The band's appearance represents one of the rare occasions on which the Velvet Underground was professionally recorded in a live setting, and while several of the performances in this set have been released in various fashions and configurations before (in particular, on the album "" and the 45th anniversary reissue of "The Velvet Underground", as well as via much lower-quality audience recordings in ""), it is the first time all of them have been collected together.  Additionally, this represents the first time much of this material has been presented in a CD version sourced directly from the original tapes, which had been considered lost for decades, and nine tracks from this collection had previously been completely unreleased in any configuration.  The resulting product has been widely praised both for its sound quality and for the power of its performances.
