The Bristol band invited the Radiohead frontman to open their All Points East show on May 24 at Victoria Park, London.
The acoustic performance will find Yorke performing songs from his solo catalogue as well as Radiohead's decades-long discography.

In addition to Massive Attack and York, All Points East will include headlining sets from Tame Impala, The Kooks, The Wombats and Kraftwerk.
Bombay Bicycle Club will also perform at the London festival, marking the British rockers' biggest show since the end of their three-year hiatus in 2019.
Yorke's solo acoustic set at All Points East was announced a few weeks after Radiohead drummer Philip Selway revealed that the band was taking a year away from the recording studio to focus on solo projects.
"There are always conversations going on, but we've always got other projects going on. This is kind of the year away from Radiohead, but we will pick that up again," he told NME, without revealing additional details about what fans can expect when they return.
While Radiohead's latest and ninth studio album "A Moon Shaped Pool" arrived in 2016, Yorke released his third solo opus, "ANIMA," last June.
The album dropped alongside a 15-minute film by Paul Thomas Anderson, which marked the filmmaker's first directional release since the Oscar-nominated "Phantom Thread."
In addition to his set at London's All Points East, Yorke will soon embark on a tour across North America and Europe.
The 16-date trek will kick off at the EagleBank Arena in Fairfax, Virginia, USA before concluding on July 13 at Berlin's Max-Schmeling-Halle.
Yorke will also share the stage with collaborators Nigel Godrich and Tarik Barr for the 2020 edition of the Coachella Valley Music and Arts Festival, which will take place across the second and third week of April (April 10 through 12 and 17 through 19) at the Empire Polo Club in Indio, California.
