The Association was one of the more underrated groups to come out of the mid- to late '60s. Creators of an enviable string of hits from 1966 through 1969, they got caught in a shift in popular culture and the unwritten criteria for significance in that field and never recovered. The group's smooth harmonies and pop-oriented sound (which occasionally moved into psychedelia and, much more rarely, into a harder, almost garage-punk vein) made them regular occupants of the highest reaches of the pop charts for two years -- their biggest hits, including "Along Comes Mary," "Cherish," "Windy," and "Never My Love," became instant staples of AM play lists, which was a respectable achievement for most musicians at the time. That same sound, along with their AM radio popularity, however, proved a liability as the music environment around them changed at the end of the decade.
