Problem: Background: Emilie Autumn Liddell (born on September 22, 1979), better known by her stage name Emilie Autumn, is an American singer-songwriter, poet, violinist, and actress. Autumn's musical style has been described by her as "Fairy Pop", "Fantasy Rock" or "Victoriandustrial". It is influenced by glam rock and from plays, novels, and history, particularly the Victorian era. Performing with her all-female backup dancers
Context: As part of a recording project, Autumn traveled to Chicago, Illinois, in 2001, and decided to stay because she enjoyed the public transportation system and music scene there. She released the 2001 EP Chambermaid while finishing Enchant--she alternatively labeled the musical style on Chambermaid as "fantasy rock" and cabaret--and wrote the 2001 charity single "By the Sword" after the events of September 11, 2001. According to her, the song is about strength, not violence; the act of swearing by the sword represents "an unbreakable promise to right a wrong, to stay true".  On February 26, 2003, she released her concept album Enchant, which spanned multiple musical styles: "new-age, pop and trip hop chamber music". Written during her late teenage years, Enchant revolved around the supernatural realm and its effect on the modern-day world. Autumn labeled it as "fantasy rock", which dealt with "dreams and stories and ghosts and faeries who'll bite your head off if you dare to touch them". The faery-themed "Enchant Puzzle" appeared on the artwork of the album; her reward for the person who would solve it consisted of faery-related items. Her bandmates consisted of cellist Joey Harvey, drummer Heath Jansen, guitarist Ben Lehl, and bassist Jimmy Vanaria, who also worked on the electronics. At the same time of Enchant's release, Autumn had several side projects: Convent, a musical group for which she recorded all four voices; Ravensong, "a classical baroque ensemble" that she formed with friends in California; and The Jane Brooks Project, which she dedicated to the real-life, 16th-century Jane Brooks--a woman executed for witchcraft.  On the night of the Enchant release party, Autumn learned that Courtney Love had invited her to record an album, America's Sweetheart, and embark on the tour to promote it. Contributing violin and vocals, Autumn appeared in Love's backing band The Chelsea--Radio Sloan, Dvin Kirakosian, Samantha Maloney, and Lisa Leveridge--on the 2004 tour. Much of Autumn's violin work did not get released on the album; she commented: "This had to do entirely with new producers taking over the project after our little vacation in France, and carefully discarding all of our sessions." She performed live with Love and The Chelsea on Late Show with David Letterman on March 17, 2004, and at Bowery Ballroom the next day. In September 2004, her father died from lung cancer, even though he had quit smoking twenty years earlier. Near the end of 2004, she was filmed for an appearance on an episode of HGTV's Crafters Coast to Coast, showing viewers how to create faery wings and sushi-styled soap--both products she sold in her online "web design and couture fashion house", WillowTech House. On December 23, 2004, she appeared on the Chicago-based television station WGN as part of the string quartet backing up Billy Corgan and Dennis DeYoung's duet of "We Three Kings".

Problem: Background: Vampire Weekend are an American rock band from New York City, formed in 2006. They are currently signed to Columbia Records. The band consists of lead vocalist and guitarist Ezra Koenig, drummer and percussionist Chris Tomson and bassist and backing vocalist Chris Baio. The band's first album Vampire Weekend (2008) - which included the singles "Mansard Roof", "A-Punk", "Oxford Comma", "Cape Cod Kwassa Kwassa" and "The Kids Don't Stand a Chance" - was acclaimed by critics for its world music influences.
Context: After remaining quiet following the conclusion of their Modern Vampires tour, on January 26, 2016, Rostam Batmanglij announced his departure from the band on Twitter. He noted that he and Koenig would continue to collaborate. Later the same day, Koenig announced that Vampire Weekend was in the studio working on their upcoming fourth album, with Batmanglij contributing to the record. The album's working title was revealed to be Mitsubishi Macchiato.  In April 2016, the band briefly performed at a rally for presidential candidate Bernie Sanders in Washington Park Square. Koenig has been a well-known supporter of Sanders, after discussions on his Beats 1 radio show, Time Crisis. The band performed live with Dave Longstreth of the Dirty Projectors, which marked their first performance as a trio.  In late 2016, Koenig was reportedly in talks to sign the band with Columbia Records, as he reportedly "hit it off" with executive, Rob Stringer. Initially, this news was regarded a rumour, until the band's website revamp in 2018, in which a Sony Music copyright appeared on the site.  In March 2017, Koenig revealed in an elaborate Instragram update that during 2016 he had spent countless hours researching and writing music in libraries with grad students. Additionally, he revealed that the album would feature a more 'spring-time' vibe and one of the songs would be entitled Flower Moon. Koenig revealed that LP4 would be partially inspired by the songwriting of country singer, Kacey Musgraves, after he attended one of her shows in September 2016. In an interview with Stereogum, he stated, "I'm the type of person who has spent hours poring over the avant-garde poetic lyrics of certain songwriters, and there was something that felt so good [about how] from the first verse, you knew who was singing, who they were singing to, what kind of situation they were in. After the show I realized there's not a ton of Vampire Weekend songs where you could listen to the first verse and immediately answer the question of who's singing and who are they singing to." Furthermore, in a September 2017 interview with Zane Lowe, Ezra briefly spoke about LP4 and stated that it was "about 80% done." He mentioned that the album would feature lead producer, Ariel Rechtshaid, with additional "guest appearances", one of which being Batmanglij. Lowe pushed Koenig for a release date, sighting Q1 2018 as a likely candidate.  The band's first show since their hiatus was confirmed on January 31, 2018, when it was announced that the band would be headlining the UK music festival End of the Road. The festival will run from August 31 to September 3 and mark Vampire Weekend's first return to the stage in 4 years. Additionally, it was announced that they would headline the 2018 Fuji Rock Festival, scheduled for July 27 to 29. The band will also be performing at Lollapalooza 2018, which runs from August 2-5, 2018.
