The Secret Commonwealth describes it's particular take on Celtic and folk music as 'Celto-eclectic.' In addition to a wealth of bawdy drinking songs, haunting ballads and instrumentals learned from the cultures of Ireland and Scotland, The Secret Commonwealth also performs many original compositions. The group has successfully combined styles as diverse as Swedish folk, bluegrass, blues, French folk, Hungarian folk, rock and roll, and Appalachian folk. The group currently has six members, all of whom write, sing, and play multiple instruments. The band's second CD 'Uninvited Guest' is a conceptual project containing nearly all original songs based around the band's interest in the supernatural, Halloween, and ghost stories.
