Mr. Tambourine Man is the debut studio album by the American rock band the Byrds and was released on June 21, 1965, by Columbia Records. The album is characterized by the Byrds' signature sound of Jim McGuinn's 12-string Rickenbacker guitar and the band's complex harmony singing. The material on the album mostly consists of cover versions of folk songs, primarily composed by Bob Dylan, and originals written or co-written by singer Gene Clark. Along with the Dylan-penned single of the same name, Mr. Tambourine Man established the band as an internationally successful act and is widely regarded by critics as representing the first effective American challenge to the chart dominance of the Beatles and other British Invasion bands during the mid-1960s.

Turn! Turn! Turn! is the second studio album by American rock band the Byrds, released on December 6, 1965, by Columbia Records. Like its predecessor, Mr. Tambourine Man, the album epitomized the folk rock genre and continued the band's successful mix of vocal harmony and jangly twelve-string Rickenbacker guitar. The album's lead single and title track, "Turn! Turn! Turn!", which was adapted by Pete Seeger from text in the Book of Ecclesiastes, had previously been arranged in a chamber-folk style by the Byrd's lead guitarist Jim McGuinn for folk singer Judy Collins' third album, but the arrangement he used for the Byrds' recording of the song utilizes the same folk-rock style as the band's previous hit singles.
