Gary Usher in the context of "Surf music"

Sunshine pop (originally called soft pop and soft rock) is a loosely defined form of pop music that was first associated with early soft rock producers and songwriters based in Los Angeles, California, during the mid- to late 1960s. Its studio-centric sound was primarily rooted in folk rock and easy listening, typically featuring rich harmony vocals and progressive elements, while lyrics combined idyllic imagery with a subtle awareness of societal change, melancholic undertones, and countercultural themes. It was among the dominating music styles heard in television, film, and commercials of the era.

Branching from the nascent California sound, the movement initially straddled multiple styles among many groups who existed briefly while adapting to evolving music trends, resulting in much crossover with bubblegum, folk-pop, garage rock, baroque pop, and psychedelia. Most groups were less successful sound-alikes of acts such as the Mamas & the Papas, led by John Phillips, and the 5th Dimension, whose songs were initially helmed by Jimmy Webb. Curt Boettcher produced numerous key records for the Association, Eternity's Children, his band the Millennium, and with collaborator Gary Usher (Sagittarius). Though the Beach Boys rarely approached the style, Brian Wilson's production of their 1966 album Pet Sounds was a foundational influence on this milieu, as were the arrangements of Burt Bacharach.

The California sound is a popular music aesthetic that originates with American pop and rock recording artists from Southern California in the early 1960s. At first, it was conflated with the California myth, an idyllic setting inspired by the state's beach culture that commonly appeared in the lyrics of commercial pop songs. Later, the sound was expanded outside its initial geography and subject matter and was developed to be more sophisticated, often featuring studio experimentation.

The sound was originally identified for harnessing a wide-eyed, sunny optimism attributed to Southern California teenage life in the 1960s. Its imagery is primarily represented by Brian Wilson and the Beach Boys, who are credited for the sound's instigation via their debut single "Surfin'" in 1961. Along with Jan and Dean, the Beach Boys encapsulated surfing, hot rod culture, and youthful innocence within music which transformed a local lifestyle into American mythology. Other proponents included songwriters and/or record producers Gary Usher, Curt Boettcher, Bruce Johnston, Terry Melcher, and Roger Christian.

Sagittarius was an American sunshine pop studio group formed in 1967, devised by record producer and songwriter Gary Usher.
