The music of Farmers Market is a mixture of Bulgarian folk music, jazz standards, popular music and humor. Farmers Market has become one of Norway's most popular live bands, playing at all kinds of venues and festivals: jazz, folk and rock.

The band Farmers Market was formed in Trondheim during the fall of 1991. All members where students of the Jazz Department at the Conservatory of Trondheim. At first Farmers Market started out as a free-jazz quintet, but soon found itself heading in a completely different direction; towards Bulgarian folk-music. Since then - this bulgarian music, with its odd meters, oriental scales and improvisational possibilities, has become one of the main musical ingredients of Farmers Market.
