As expected, Radiohead have bumped up the hype for OKNOTOK, the 20th anniversary edition of OK Computer that's arriving June 23, by releasing "I Promise." You can watch the video for it above.

The song received its world premiere earlier today on Steve Lamacq's 6 Music Recommends program on BBC 6. The band played it on numerous occasions during their 1996 tour. This marks the first time the studio version has been officially aired. Last week, a thread on Reddit speculated that it would be the lead track from the collection

"I Promise" joins "Man of War" and "Lift" as the three previously unreleased songs found on OKNOTOK. The other eight tracks found on the second disc are comprised of b-sides. Session archives and demos from OK Computer can be found on a 90-minute cassette (with download card) included in a Boxed Edition that the band is also putting out.

It's possible that Radiohead didn't put out "I Promise" because its lyrics, which appear to center around a couple's argument, didn't fit in with the album's overall themes of technology, globalization and alienation. Frontman Thom Yorke once reportedly said that the song reminds him of Joy Division, and now listeners can judge for themselves if the comparison is apt by listening in the widget below.

The band is set to begin the European leg of its 2017 tour next week in Oslo. Opening up for them will be Junun, a side project of guitarist Jonny Greenwood.
