KRSIX is an instrumental sextet led by saxophonist Kasper Rietkerk. Their narrative music is most reminiscent of something between Brian Blade’s Fellowship of Acoustic and Radiohead. They did their first few shows in the spring of 2021 in London, where they are┬ábased. The music is rooted in jazz but you can hear influences from rock to folk and blues music. All the music is written and arranged by Kasper and the songs are mostly influenced by things that he observed and experienced after he moved to London.

Kasper performs with Max McLeish (trombone), Alex Lockheart (guitar), Benji Bown (piano), Jonah Evans (drums) and Toby Yapp (double bass).
