Originally from New Zealand, Mark is a peripatetic performer of Celtic and experimental music. But he's also a luthier (albeit currently inactive). Top: an 8-string solidbody electric bouzouki; a 10-string fan-fret cittern (inspired by a similar instrument built by fellow New Zealander Davy Stuart); and an 8-string mandolin built for Juliette Primrose. Bottom: two 10-string electric bouzoukis co-built with Mark's former partner, American luthier G. D. Armstrong, who is making some very similar instruments.
