"Two Sevens Clash" is the debut album by roots reggae band Culture, recorded with producer Joe Gibbs at his own Joe Gibbs Recording Studio in Kingston, Jamaica, in 1976, and released on Gibbs' eponymous label in 1977. The album's title is a reference to the date of 7 July 1977 - the day when sevens fully 'clashed' (seventh day, seventh month, seventy-seventh year). The album was reissued in 1988 with different cover art, and with the track listing altered with the last five tracks of the ten tracks listed first, and tracks 1–5 becoming tracks 6–10. To mark its 40th anniversary, the album was reissued again in 2017. This version features an additional disc of remixes and dub versions. New sleeve notes were written by Don Letts.
