Rare Silk was an American vocal jazz group that was active during the 1980s. MaryLynn Gillaspie and her sister, Gaile, grew up in southern California. Their father played trumpet, and from an early age they heard big band music and Ella Fitzgerald. In 1978, they were working as waitresses in Boulder, Colorado, with Gaile also singing at a local club. After they met another singer, Marguerite Juenemann, they formed Rare Silk. They sang on a local radio station and in clubs, sometimes dressed like the Andrews Sisters.
