“Pressure Drop” is a song recorded in 1969 by The Maytals for producer Leslie Kong. The song appears on their 1970 album Monkey Man (released in Jamaica by Beverley’s Records) and From the Roots (released in the UK by Trojan Records). “Pressure Drop” helped launch the band’s career outside Jamaica when the song was featured in the soundtrack to the 1972 film The Harder They Come, which introduced reggae to much of the world. In 2004, Rolling Stone rated the song No. 446 in its list of the 500 Greatest Songs of All Time.
The song has appeared on the soundtracks to the films 50 First Dates and This Is England and features on the K-Jah West radio station in the video game Grand Theft Auto: San Andreas. – Wikipedia
