In Cold Blood (alt-J song)

"In Cold Blood" is a song by British indie rock band alt-J. It is the second track and second single from their third studio album, Relaxer, and was released as a digital single on 29 March 2017 by Infectious Music and Atlantic Records. The song was written by Joe Newman, Gus Unger-Hamilton, and Thom Sonny Green and produced by Charlie Andrew. It features a brass section recorded at Abbey Road Studios in London and a Casiotone the band purchased for £1.05 on eBay. The song's title is a reference to the novel of the same name by American novelist Truman Capote. The song's composition dates back to when the band started during their studies at the University of Leeds.

Composition and lyrics
In an interview with NPR, the band said: This song was started when we were still students in Leeds, finally finished in the sessions for this album. Sometimes it happens that way. The title comes from the book of the same name by Truman Capote — however, this was mostly because it sounded good rather than due to the song being about mass murder. We recorded the brass section at Abbey Road Studios in North London, which was an amazing experience. The song starts with the eight digit binary phrase: "zero one one one zero zero one one" (01110011), which is 163 (octal), 115 (decimal), and 73 (hex), which translates to a lowercase "s" under the ASCII system. It is unclear what this means, although the band labeled a teaser for the song "3WW" with the binary ASCII encoding “00110011 01110111 01110111”. If extended to use all of the numbers in the line we get the number 01110011(cry)0 (and I'm Hearing) 111 which is 1847 - the year that Samuel Colt sold his patented revolvers to the Texas rangers in the war against Mexico.

Music video
The music video for the song was released on 9 May 2017. It was directed by Casper Balslev, who had previously directed videos for Marina and the Diamonds and MØ. The video is narrated by Iggy Pop, frontman of The Stooges.

Critical reception
"In Cold Blood" received favorable reviews from contemporary music critics. Robin Murray of Clash called it "both straight-forwardly melodic and fascinatingly complex, the interweaving vocals underpinned by bleeping electronics and flashes of brass."
