"Arabella" is a song by English indie rock band Arctic Monkeys from their fifth studio album, AM (2013). The song was confirmed as the album's fifth single by the band and their label Domino and impacted radio in Italy on 28 January 2014 and the United Kingdom on 10 March 2014. A physical 7" vinyl single was also planned for release on 28 March 2014, but was ultimately cancelled.
"Arabella" was played live for the first time on 30 August 2013, during Zurich Openair festival performance, which was a part of the AM Tour. The band often play part of Black Sabbath's "War Pigs" during live performances of the song, done to give Alex Turner time to equip a guitar for the solo. The part "War Pigs" is played due to the similarities between the riffs of the two songs.
In September 2013, following the release of AM, "Arabella" charted at number 155 on the UK Singles Chart, number 26 on the UK Indie Chart, and number 7 on the Ultratip chart of Belgium's Flanders region. Following the announcement of its single release in March 2014, the single re-entered the UK Singles and Indie charts, peaking at numbers 70 and 9 respectively. "Arabella" was added to the BBC Radio 1 playlist on the B-list on 10 February 2014.
