"Real Rock" is a 1967 instrumental reggae song by Sound Dimension, one of the house bands of producer Coxsone Dodd's famous Studio One. It is significant for giving rise to perhaps the most popular reggae riddim of all time, having been versioned hundreds of times by artists ranging from The Clash to KRS-One to 311. According to a 2004 New York Times article, Dodd considered the song his crowning achievement. The riddim's signature three-note Hammond organ figure was played by the legendary Jackie Mittoo.
