Eva Marie Cassidy (February 2, 1963 – November 2, 1996) was an American vocalist and guitarist known for her interpretations of jazz, blues, rock, and pop classics. In 1992, she released her first album, The Other Side, a set of duets with go-go musician Chuck Brown, followed by the 1996 live solo album titled Live at Blues Alley. Although she had been honored by the Washington Area Music Association, she was virtually unknown outside her native Washington, DC. She died of melanoma in 1996.
Two years after her death, Cassidy's music was brought to the attention of British audiences, when her versions of "Fields of Gold" and "Over the Rainbow" were played by Mike Harding and Terry Wogan on BBC Radio 2. Following the overwhelming response, a camcorder recording of "Over the Rainbow", taken at Blues Alley in Washington by her friend Bryan McCulley, was shown on BBC Two's Top of the Pops 2. Shortly afterwards, the compilation album Songbird climbed to the top of the UK Albums Charts, almost three years after its initial release. The chart success in the United Kingdom and Ireland led to increased recognition worldwide. Her posthumously released recordings, including three UK number 1 records, have sold more than ten million copies. Her music has also charted top 10 positions in Australia, Germany, Sweden, Norway and Switzerland.
