In June 2017, Radiohead released a 20th-anniversary "OK Computer" reissue, "OKNOTOK 1997 2017", comprising a remastered version of the album, B-sides, and three previously unreleased tracks: "I Promise", "Man of War" and "Lift". Radiohead promoted the reissue with music videos for the three new tracks. "OKNOTOK" debuted at number two on the UK Album Chart, boosted by Radiohead's televised Glastonbury performance that week, and reached number 23 on the US "Billboard" 200. Yorke and Jonny Greenwood performed a benefit concert in Le Marche, Italy, in August 2017 following the August 2016 Central Italy earthquake. In September, the nature documentary series "Blue Planet II" premiered featuring a new version of the "King of Limbs" track "Bloom", created with composer Hans Zimmer.
