For some time, and for two released albums, “Ballrogg” (2008) and “Insomnia” (2010) Ballrogg was the name of the duo formed by clarinetist and saxophonist Klaus Ellerhusen Holm and double bassist Roger Arntzen. Initially identified by a captivating approach exploring the music of Jimmy Giuffre and Eric Dolphy and hinting to the non-linear structures patented by indeterminist new music composers like Morton Feldman. Meanwhile, in 2011 and for their next albums “Cabin Music” (2012) and “Abaft The Bram (2017) Ivar Grydeland joined the project. He brought with him a strong country & western influence and the music gradually shifted in direction of the currently described “free chamber Americana”. The Swedish guitarist extraordinaire David Stackenäs (Circadia, SEVAL) has now replaced Grydeland and things got even more complex. Stackenäs has since his debut in 2000 developed a very personal style and due to his versatility he has collaborated with pretty much everybody in the global creative jazz/improv scene. Stackenäs has previously toured with Ballrogg on several occasions, both in Europe and the United States.

“Ballrogg distances itself from traditional improv while shunning excessive extrovertism and friendliness. This allows for considerable friction.”

“The ability of the North European scene to reinvent «American classical music» and even to reinvent the American folk roots is legendary, and here we have one precious example.” – Clean Feed (PT)
