Fourplay is a contemporary American smooth jazz quartet. The original members of the group were Bob James (keyboards), Lee Ritenour (guitars), Nathan East (bass), and Harvey Mason (drums). In 1997, Lee Ritenour left the group and Fourplay chose Larry Carlton as his replacement. In 2010, Larry Carlton left Fourplay and was replaced by Chuck Loeb, who died on July 31, 2017.

Grammy-nominated supergroup Fourplay has enjoyed consistent artistic and commercial success by grafting elements of R&B and pop to jazz, appealing to a broad mainstream audience.

Their first record, 1991's Fourplay, sold over a million copies and remained at the number one position on the Billboard contemporary jazz chart for 33 weeks. Their next LP, 1993's Between the Sheets, reached number one, went gold, and received a Grammy nomination. In 1995, their third gold album, Elixir, also reached the number one position and remained on the chart for more than 90 weeks. The band celebrated its 25th anniversary with the release of the album Silver in 2015, which featured former members Ritenour and Carlton as guest artists.
