Kingfisher Sky is a Dutch progressive metal band from Netherlands, created and led by drummer Ivar de Graaf.

The history of Kingfisher Sky started in 2001, after drummer Ivar de Graaf left Within Temptation, to pursue his own musical interests, and founded Jambone, with the idea to cover classic rock bands.

At an early stage, Eric Hoogendoorn was chosen as the permanent bassist and guitarist Daan Janzing, who was introduced by Ruud Jollie, was recruited next.

Within the scope of a special show in their hometown, Kingfisher Sky was joined by classical cellist Maaike Peterse, who played along on "Big Fish".

Ivar's progressive rock and traditional folk music influences collided with Judith's classical conservatory background, and also her preference for soul.

Combined with their mutual love for bands and artists, like Aretha Franklin, Porcupine Tree, Jethro Tull, Peter Gabriel, Kate Bush, Tori Amos, Cecilia Bartoli, Mother's Finest, King's X, Skunk Anansie, Anouk, Heart, Clannad, Mike Oldfield and Pink Floyd, new songs were written.
