Wherligig, the Koons family band, performs Celtic and Nordic traditional music on often obscure traditional and historical instruments, many of which are made by father and guitarist Ken Koons. Wherligig performs as a quartet with the whole family, and the boys break away and perform as a duo as well.

Turlough O'Carolan, Alawon John Thomas, Byss Calle, Magnus Lundqvist, various other traditional repertoires from Nordic lands and the British Isles.
