Many thanks to Mordi at the Blow Up Doll music blog for turning me onto this duo.
Wendy and Bonnie Flower were an American singing sister duo, who recorded the album, Genesis, in 1969 for Skye Records.
The album was produced by Gary McFarland. At the time, McFarland was part owner of the Skye label, along with Latin percussionist Cal Tjader (who was Wendy and Bonnie's godfather) and jazz guitarist Gábor Szabó.
Wendy and Bonnie grew up in Millbrae, California, in the San Francisco Bay suburbs. Their parents, Art and Jeane Flower, were professional musicians. In 1967, Wendy played and recorded with an early San Francisco psychedelic band called Crystal Fountain; Bonnie later joined the band as drummer. The following year, Tjader heard some of the Flower sisters' acoustic home demos and arranged a recording session with Skye. The sisters, who were teens at the time the album was recorded, composed all the songs. McFarland served as arranger on the sessions, crafting a post-psychedelic soft rock sound with Brazilian overtones. Musicians who performed on the album included guitarist Larry Carlton, drummer Jim Keltner, and keyboardist Mike Melvoin.
The Skye label went bankrupt shortly after the album's release. In 1971, while planning for additional recording with the Flower sisters, McFarland was murdered in mysterious circumstances in a New York bar.
In the early 1970s, Wendy and Bonnie provided background vocals on two Cal Tjader albums for Fantasy Records. Thereafter, the sisters pursued separate careers in music and entertainment, but did not record together again.
