Alison Maria Krauss (born July 23, 1971) is an American bluegrass-country singer and musician. She entered the music industry at an early age, winning local contests by the age of 10 and recording for the first time at 14. She signed with Rounder Records in 1985 and released her first solo album in 1987. She was invited to join the band with which she still performs, Alison Krauss and Union Station, and later released her first album with them as a group in 1989.
She has released fourteen albums, appeared on numerous soundtracks, and she sparked a renewed interest in bluegrass music in the United States. Her soundtrack performances have led to further popularity, including the O Brother, Where Art Thou? soundtrack, and the Cold Mountain soundtrack, which led to her performance at the 2004 Academy Awards.
