The Kingston Trio is an American folk and pop music group that helped launch the folk revival of the late 1950s to late 1960s. The group started as a San Francisco Bay Area nightclub act with an original lineup of Dave Guard, Bob Shane, and Nick Reynolds. It rose to international popularity, fueled by unprecedented sales of 33⅓ rpm long-playing record albums, and helped to alter the direction of popular music in the U.S.
The Kingston Trio was one of the most prominent groups of the era's pop-folk boom that started in 1958 with the release of their first album and its hit recording of "Tom Dooley", which sold over three million copies as a single. The Trio released nineteen albums that made Billboard's Top 100, fourteen of which ranked in the top 10, and five of which hit the number 1 spot. Four of the group's LPs charted among the Top 10 selling albums for five weeks in November and December 1959, a record unmatched for more than 50 years, and the group still ranks after half a century in the all-time lists of many of Billboard's cumulative charts, including those for most weeks with a number 1 album, most total weeks charting an album, most number 1 albums, most consecutive number 1 albums, and most top ten albums.
