Background: Napalm Death are a British extreme metal band formed in Meriden, West Midlands, England, in 1981. While none of its original members remain in the group since December 1986, the lineup of vocalist Mark "Barney" Greenway, bassist Shane Embury, guitarist Mitch Harris and drummer Danny Herrera has remained consistent of the band's career since 1992's Utopia Banished, although, from 1989 to 2004, Napalm Death were a five-piece band after they added Jesse Pintado as the replacement of one-time guitarist Bill Steer; following Pintado's departure, the band reverted to a four-piece rather than replace him. Napalm Death are credited as pioneers of the grindcore genre by incorporating elements of crust punk and death metal, using a noise-filled sound that uses heavily distorted, down-tuned guitars, grinding overdrive bass, high speed tempo, blast beats, and vocals which consist of incomprehensible growls, or high-pitched shrieks, extremely short songs, fast tempos, and sociopolitical lyrics. The band's debut album Scum, released in 1987 by Earache Records, proved substantially influential throughout the global metal community.
Context: In February 2011, Napalm Death appeared in an episode of E4's Skins. Napalm Death entered Parlour Studio in Kettering, with producer Russ Russell to begin working on a new album. Also in 2011, they recorded the single "Legacy Was Yesterday". Napalm Death released their fifteenth studio album, Utilitarian, on 27 February 2012 in Europe and 28 February in North America via Century Media. In March 2012, Napalm Death headlined the Metal Mayhem IV festival organized by "Defenders of Metal" in Nepal. This was the first time Napalm Death played in Nepal.  Napalm Death were scheduled to play a special one-off show at the Victoria and Albert Museum in London, on 22 March 2013. The show was eventually cancelled at the Victoria and Albert Museum, due to concerns that the noise levels could damage parts of the museum. The show was relocated to the De La Warr Pavilion in Bexhill, and was performed on 29 November 2013. The performance was a collaboration with ceramicist and Victoria and Albert Artist in Residence Keith Harrison. The show featured 10 large-scale wooden speakers filled with liquid clay that were left to solidify. When the band began to play, the clay inside the speakers was expected to vibrate, causing the speakers to crack and eventually explode. The actual performance was considered anticlimactic, as the speakers withstood the sonic vibration.  In April 2014, the band released a cover of the Cardiacs' song "To Go Off and Things" via Bandcamp. All proceeds from the single went towards Cardiacs frontman Tim Smith's recovery from a simultaneous heart attack/stroke he suffered in 2008. The band announced on 5 November 2014, via Facebook that due to an illness in the family, Mitch Harris would be taking a hiatus from the band, to be replaced by various guitarists on their tour. Napalm Death's sixteenth studio album, Apex Predator - Easy Meat, was released on 26 January 2015. On 4 July, a Nepal Charity Event track from the Apex Predator sessions called "Earth Wire" was released on their page.
