Endless Harmony Soundtrack is an anthology album of previously unheard material by The Beach Boys, originally released by Capitol Records in August 1998. Named for Bruce Johnston's song on the 1980 album Keepin' the Summer Alive, it was designed as a tie-in with the band's biographical documentary of the same name. The soundtrack was re-issued in March 2000 with some remixing and different artwork, while the original 1998 edition went out of print shortly thereafter.

Michael Edward Love is an American singer and songwriter who was the lead vocalist of the Beach Boys which he co-founded with his cousins Brian, Dennis, and Carl Wilson and their friend Al Jardine. Characterized by his nasal tenor and occasional bass-baritone singing, Love has been one of the band's vocalists and lyricists for their entire career, contributing to each of their studio albums and serving as their frontman for live performances. During the mid-1960s, he was one of Brian's main collaborators, contributing lyrics to hit records such as "Fun, Fun, Fun" (1964), "I Get Around" (1964), "Help Me, Rhonda" (1965), "California Girls" (1965), and "Good Vibrations" (1966).
