The current lineup consists of Lief Sørbye (mandolin, vocals), Adolfo Lazo (percussion), Lee Corbie-Wells (fiddle, vocals), Nikolay Georgiev (guitar), and Hugh Caley (bass, backup vocals), with members from around the world: Lief from Oslo, Norway, Adolfo Lazo from Havana, Cuba, Lee Corbie-Wells from San Francisco, California, and Hugh Caley from Detroit, Michigan and Nikolay Georgiev from Pleven, Bulgaria.
The festival is called Karfluki Fest, and has featured such artists as It's A Beautiful Day, Big Brother and the Holding Company, Fairport Convention, Shana Morrison, Wicked Tinkers and Fishtank Ensemble, in addition to an array of side show acts such as belly dancers, a sword swallower, jugglers, acrobats and fire dancers.
