Sunshine pop

Sunshine pop (originally known as soft pop)[3] is a name given many years later to a subgenre of pop music that originated in Southern California in the mid-1960s. Viewed later as perhaps influenced by easy listening and advertising jingles, sunshine pop acts seem to combine nostalgic or anxious moods with "an appreciation for the beauty of the world".[1] The category largely consists of lesser-known artists who imitated more popular groups such as the Mamas & the Papas and the 5th Dimension. While the Beach Boys are noted as prominent influences, the band's own music was rarely representative of the genre.[1][2]

Sunshine pop enjoyed mainstream success in the latter half of the decade, with many of its top 40 hits peaking in the spring and summer of 1967, especially just before the Summer of Love. Popular acts include the Turtles and the Association. Other groups, like the Millennium, Sagittarius, and the Yellow Balloon were less successful but gained a cult following years later[4] with albums like Begin (Millennium, 1968) and Present Tense (Sagittarius, 1968) being sought after on the collectors’ market.[1]
