Founded in 1968 as Power of Music, the band toured after successful live performances in their Scottish homeland and in Germany as the opening act for big names of the time such as Fleetwood Mac, Deep Purple and Free. Renamed Northwind, the quintet with singer and guitarist Brian Young, guitarist Hugh Barr, keyboardist Colin Somerville, bassist and singer Tom Brannan from Glasgow, and drummer Dave Scott from Edinburgh, recorded the demo album Peaceful for the Beatles’ Apple label. This led to a record deal in 1971 with the EMI sub-label Regal Zonophone. In the same year, they recorded their debut album Sister, Brother, Lover.... at London’s Sound Techniques and Regent Sound Studios, with Tony Chapman as producer and Tom Allom as sound engineer.

It was released in August 1971 in England and France. The structural cover, with its very impressive atmosphere of the coast at sunset, perfectly captures their idyllic, progressive soft rock, partly acoustic, with calm, melodious organ and guitar passages as well as soulful vocals. Although the album sold over 10,000 copies in both countries and the band continued to tour successfully, they received little support from their management and record label. As a result, they disbanded a year after the album’s release. Their first and only LP has since become an extremely sought-after collector’s item.
