Ballrogg is a trio of Klaus Ellerhusen Holm on alto saxophones, clarinet, electronics and field recordings, Roger Arntzen on double bass and Ivar Grydeland on pedal steel guitar, acoustic guitar, banjo and radio. Ballrogg started out as a duo with bass and reeds, and has previously released two albums on Bolage, drawing influences from European contemporary music as well as American avantgarde.

Extended to a trio with the great Norwegian guitar and pedal steel guitar player Ivar Grydeland (Huntsville, Dans Les Arbres, Hanne Hukkelberg), and signed to Hubro, Ballrogg is expanding their already almost cinematic sound universe into an even bigger texture of vibrant and sustained world of electric and acoustic strings, sax, clarinet and double bass.

Ballrogg has toured in the United States, Europe, Russia and Japan.
