Not only is this 9 piece instrumental band regarded as one of the most exciting and innovative in Norway, the members are all involved in other musical projects and have in one way or another contributed to almost every significant recording to come out of that part of the world in the last few years. It has been this strong involvement with different projects, and different musical styles and sounds which is the key to the unique sound of Jaga Jazzist. With no boundaries and an arsenal that includes trumpet, trombone, electric guitars, bass, tuba, bass clarinet,saxes, keyboards, vibraphone and a rack of electronics, Jaga Jazzist create timeless music. Melodic, hypnotizing, delicate and subtle.
