What makes Silly Sisters by Maddy Prior notable?

'Silly Sisters' is significant for its role in reviving interest in traditional British folk music during the 1970s, a time when such genres were often overshadowed by rock and pop. The album was well received and helped establish both Prior and Tabor as key figures in the British folk revival, influencing countless artists who followed them. When 'Silly Sisters' was released in 1976, Maddy Prior was already known as the lead singer of Steeleye Span, a prominent British folk rock band. This album marked her first collaboration with fellow folk artist June Tabor, showcasing their individual styles while also signaling Prior's interest in exploring more traditional folk themes outside her band work.
