Culture - Two Sevens Clash, 1977

Two Sevens Clash is the debut album by roots reggae band Culture, recorded/produced by Joe Gibbs at his own Joe Gibbs Recording Studio in Kingston in 1976, and released on Gibbs' label in 1977.
The album's title is a reference to the date of July (07) 7, 1977.

Singer Joseph Hill said "Two Sevens Clash," Culture's most influential record, was based on a prediction by Marcus Garvey, who said there would be chaos on July 7, 1977, when the "sevens" met. With its apocalyptic message, the song created a stir in his Caribbean homeland and many Jamaican businesses and schools shuttered their doors for the day.[5][6]

The liner notes of the album read: "One day Joseph Hill had a vision, while riding a bus, of 1977 as a year of judgment -- when two sevens clash -- when past injustices would be avenged. Lyrics and melodies came into his head as he rode and thus was born the song "Two Sevens Clash" which became a massive hit in reggae circles both in Jamaica and abroad. The prophecies noted by the lyrics so profoundly captured the imagination of the people that on July 7, 1977 - the day when sevens fully clashed (seventh day, seventh month, seventy-seventh year) a hush descended on Kingston; many people did not go outdoors, shops closed, an air of foreboding and expectation filled the city."
