The recently-reformed group will perform at an as-yet-unnamed venue in the capital for randomly-selected fans who bought tickets to their recent Heaton Park shows.
"The Stone Roses are playing an intimate gig this evening in London," the band confirmed on their official Facebook page.
"Entry to this show is free but strictly limited. We will be giving away a number of tickets today to fans from the London area who bought tickets for Heaton Park."
The message continued: "If you are one of those randomly chosen you will receive an email (via the email address you provided when purchasing Heaton Park tickets) in the next hour offering you the opportunity to claim a pair of tickets.
"The first people to immediately reply to this email will then be allocated the tickets and will receive details of how and where to collect their pair of tickets for the show from."
