IN: David Jon Gilmour,  (born 6 March 1946) is an English guitarist, singer and songwriter best known as a longtime member of the progressive rock band Pink Floyd. He joined the group as guitarist and co-lead vocalist in 1968, effectively as a replacement for founder member Syd Barrett, who was dismissed from the band shortly afterwards. Pink Floyd subsequently achieved international success with the concept albums The Dark Side of the Moon, Wish You Were Here, Animals, and The Wall. By the early 1980s, they had become one of the most critically acclaimed and best-selling acts in the history of popular music; it was estimated that by 2012 the band had sold over 250 million records worldwide, including 75 million units sold in the United States.

Gilmour was responsible for bringing Kate Bush to public attention. While she was still at school, her family produced a demo tape with over 50 of her compositions, which was turned down by record labels. Gilmour received a copy of the demo from Ricky Hopper, a mutual friend of Gilmour and the Bush family. Impressed with what he heard, Gilmour helped the sixteen-year-old Bush get a more professional-sounding demo tape recorded that would be more saleable to the record companies. Three tracks in total were recorded and paid for by Gilmour. The tape was produced by Gilmour's friend Andrew Powell (who would go on to produce Bush's first two albums) and sound engineer Geoff Emerick. Gilmour then arranged for EMI executive Terry Slater to hear the tape. Slater was impressed by the tape and signed her.  Gilmour is credited as executive producer on two tracks on her debut album The Kick Inside, including her second single "The Man with the Child in His Eyes". He performs backing vocals on "Pull Out the Pin", on her fourth album, The Dreaming, and plays guitar on "Love and Anger" and "Rocket's Tail" on her sixth, The Sensual World.  In March 1987, Bush, notorious for the rarity of her live performances, sang "Running Up That Hill" at The Secret Policeman's Third Ball with Gilmour on guitar. A three DVD set of The Secret Policeman's Balls benefit concerts that includes their performance was released in 2009. In 2002, she performed "Comfortably Numb", singing the part of the doctor, at Gilmour's concert at the Royal Festival Hall in London.

IN: 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.

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.
