|The Washington Squares|
Folk music is probably most identified with the protest era of the 1960s, through musicians such as Bob Dylan, Joan Baez and Peter Paul & Mary, but folk has both strong roots in previous eras, and also often reappeared throughout subsequent eras. The '80s folk revival was represented by such artists as Traci Chapman, Suzanne Vega, the Indigo Girls, Michelle Shocked, and the Washington Squares. I vividly remember Chapman's "Fast Car," and Suzanne Vega's "Luka," serious songs dealing with serious issues, on the radio when I first started college.
Above is a great 1983 report about the folk scene at the legendary Folk City in New York's Greenwich Village, which now featured '80s folk revivalists The Washington Squares. (Thanks and acknowledgement to Dnikdoog1.)
