With its apocalyptic message, the song created a stir in his Caribbean homeland and many Jamaican businesses and schools closed for the day.

[6][7] 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."

Music critic Robert Christgau named the album one of the few import-only records from the 1970s he loved yet omitted from Christgau's Record Guide: Rock Albums of the Seventies (1981).
