Alison Maria Krauss is an American bluegrass-country singer and fiddler. She entered the music industry at an early age, competing in local contests by the age of eight 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 Union Station, releasing her first album with them as a group in 1989 and performing with them ever since.

A fiddle is a bowed string musical instrument, most often a violin. It is a colloquial term for the violin, used by players in all genres, including classical music. Although in many cases violins and fiddles are essentially synonymous, the style of the music played may determine specific construction differences between fiddles and classical violins. For example, fiddles may optionally be set up with a bridge with a flatter arch to reduce the range of bow-arm motion needed for techniques such as the double shuffle, a form of bariolage involving rapid alternation between pairs of adjacent strings. To produce a "brighter" tone than the deep tones of gut or synthetic core strings, fiddlers often use steel strings. The fiddle is part of many traditional (folk) styles, which are typically aural traditions—taught "by ear" rather than via written music.
