A Head Full of Dreams is the seventh studio album by the British rock band Coldplay. It was released on 4 December 2015, by Parlophone in the United Kingdom, and by Atlantic Records in the United States. Coldplay recorded the album from late 2014 to mid 2015, right after the completion of their previous album Ghost Stories, with a markedly different style and sound from its predecessors. For various songs, Coldplay collaborated with Beyoncé, Noel Gallagher, Tove Lo, Khatia Buniatishvili and Merry Clayton. The album was produced by Rik Simpson and Stargate. The album also features a sample of President Barack Obama singing "Amazing Grace" at Clementa C. Pinckney's funeral on the song "Kaleidoscope".
The album received mixed reviews from critics. Commercially, it topped the UK Albums Chart, and peaked at number two in the United States, Australia, Canada, and Italy where it was held off the top spot by Adele's 25. At the 2016 Brit Awards the album was nominated for British Album of the Year. It was the eighth-best-selling album of 2015 with 1.9 million copies sold worldwide, according to the International Federation of the Phonographic Industry. It was the ninth-best-selling album of 2016, with 1.4 million copies sold worldwide, according to the International Federation of the Phonographic Industry. As of November 2017, the album has sold over six million copies worldwide. It was supported by five singles: "Adventure of a Lifetime", "Hymn for the Weekend", "Up & Up", the title track, and "Everglow". A 5.1 Surround Blu-ray Audio version of the album was released via the band's website on 23 September 2016. The album was promoted by the successful A Head Full of Dreams Tour, that lasted two years.
Coldplay began working on A Head Full of Dreams in late 2014 after promoting their sixth album Ghost Stories. The album has a markedly different style and sound from its predecessors. In an interview with Radio 2 DJ Jo Whiley in December 2014, guitarist Jonny Buckland and bass guitarist Guy Berryman gave a hint as to the difference between A Head Full of Dreams and its predecessor – Buckland called it the "night to the day", comparing the style of Ghost Stories to the expected uplifting theme of A Head Full of Dreams. Lead singer Chris Martin hinted at the style of the album by saying that the band was trying to make something colourful and uplifting. He also stated that it would be something to "shuffle your feet" to.
On 26 September 2015, the band performed at the Global Citizen Festival 2015 in New York City, playing a six-song set, including a new song called "Amazing Day". The band's producer Rik Simpson confirmed that the song would be on the new album. On 21 November 2016 frontman Chris Martin announced new material to be released for 2017 via Twitter, it would be named Kaleidoscope EP.(wiki)
