Keith Richards has released a new single, "Substantial Damage," from his forthcoming LP Crosseyed Heart.

Richards previously unveiled a viral campaign for fans looking to get an early taste of his upcoming album.

Richards is placing four temporary plaques in London, each "celebrating a site of significance to the Rolling Stones guitarist's life."

Richards will share the locations via Twitter and Facebook for fans to find.

Each plaque has a unique password to be submitted at the Crosseyed Heart website, and each password unlocks one song.

The plaque for "Substantial Damage" was found at 33 Chastilian Rd. in Dartford, where the Rolling Stones guitarist lived as a baby.

Fans have already unlocked the first song, "Amnesia," and the second location was tweeted out earlier this week.

Crosseyed Heart lands September 18.
