Odd Future Wolf Gang Kill Them All have announced that they will hold the two shows on April 29, the same day as the royal wedding.
The first show will be held at London's Village Underground with doors opening at 2.30pm. The second performance will be held at Relentless Garage, starting at 10.30pm.
The 11-piece collective, who are from Los Angeles, will then play at this year's Camden Crawl on May 1.
Odd Future member Frank Ocean was recently in the recording studio with Beyoncé working on material for her new album.
