Ahead of their OK Computer 20th-anniversary release, OKNOTOK, Radiohead have shared a previously unreleased track titled “I Promise.”

Radiohead also shared the official video directed by Michal Marczak, a creepy visual featuring a robotic head taking a trip through town on a bus. “I Promise” is only the first of three unreleased tracks to be unveiled as part of the OKNOTOK compilation with “Lift” and “Man of War” to follow.
