The band consists of Kazuhiro Inaba from Japan (guitar); Arnold Lasseur from the Netherlands (mandolin); Jan Johansson from Sweden (fiddle); Hamish Davidson from Australia (fiddle); Sean McKerr from Ireland (acoustic bass); and Butch himself on banjo. His father, the late Calvin Robins, who was a close friend of Bill Monroe, was a major influence in introducing Butch to visitors from outside the US and encouraging him to make contact with different cultures.
