Tennis is an American indie pop band from Denver, Colorado, United States, made up of husband-and-wife duo Alaina Moore and Patrick Riley. The duo formed in 2010, and released their debut album, Cape Dory, in 2011. Their second album, Young & Old, was released the following year. Their third release, Ritual in Repeat (2014), was released on Communion records. The band's fourth album, Yours Conditionally, was released in 2017, followed by Swimmer in 2020. 　　Alaina Moore (born May 9, 1985) and Patrick Riley (born September 9, 1986) met in a philosophy class while both were students at the University of Colorado, Denver in 2008. The couple started the band after they returned from an eight-month sailing expedition down the Eastern Atlantic Seaboard after their graduation. Moore had initially intended to go to law school. The songs on the band's first album would come to document their experiences sailing. Prior to forming Tennis, Moore's earliest singing experience was in church choirs during her youth.
