"Thunder" is a song by Prince and The New Power Generation, from the 1991 album Diamonds and Pearls. It was issued as a limited, individually numbered 12-inch single picture disc in the UK only, and the edited version was available only on the promotional single. The lyrics can be interpreted as referring to the night Prince decided to withdraw The Black Album, when he was rumored to have suffered a bad ecstasy trip. This is the first single cover to feature Mayte, sitting at the lower left.
