GreenMan centers its music in the traditional Celtic music of Ireland, Scotland, Wales, and Brittany. The melding of these traditional influences, some hundreds of years old, with contemporary arrangements, has created a unique sound in this four-piece band.

GreenMan members started the band because of a mutual interest in the sounds and music of Ireland. They realized that some of the best music of Ireland and the Celtic tradition was lost to American audiences. While many Americans are familiar with classics like "Danny Boy," most have little knowledge of other traditional songs and ballads like "The Wild Rover," and "The Wind That Shakes The Barley."

On St. Patricks Day in 1997, the band GreenMan first appeared. Since that time, GreenMan has played for school children, Christmas parties, local pubs, Irish heritage events, the Fargo Celtic Festival and the Norsk Hostfest. GreenMan sees these events as a chance to demonstrate the vitality of traditional music as its interest grows and adapts to the twenty-first century.
The name "GreenMan" originates from the ancient Celtic myths. The Green Man was the wise man of the forest and represented the cycle of life found in nature. Green Man statues and icons can be found all over continental Europe and the British Isles on cathedrals, castles, and in small village parks. At Green Man festivals, dancing and music, coordinated with spring planting and fall harvests, ensure bountiful crops. Though essentially a myth, connections between the Green Man and Robin Hood, or the stories of King Arthur and the Holy Grail, abound in folk tales and legend.
