One of the drawbacks to marriage can be a lack of privacy. Then again, if you’re Patrick Riley and Alaina Moore—the husband-and-wife team behind Denver indie-rock band Tennis—sometimes snooping unearths the backbone of your next record. While rooting around in an old computer file, Riley stumbled across an acoustic piano tune lead singer Moore had recorded years earlier. The track became “In the Morning I’ll Be Better,” a single on the group’s fourth album, Yours Conditionally. Moore credits the song’s soulful melody to the influence of singer-songwriters Carole King and Laura Nyro, whose work Moore listened to while recording it. “We’re trying to break out of the girl-group sound,” Moore says. Yours Conditionally kicks off an important spring for Tennis: After the album comes out this month, the duo will travel to California to play the Coachella Valley Music and Arts Festival for the first time. But Tennis’ 2017 is already off to a good start, with “In the Morning” being hailed as “Your new favorite chill-wave escape” by New York Magazine. Not bad for a song left to languish inside a hard drive.
