KRSIX is an instrumental sextet led by London-based saxophonist Kasper Rietkerk. Their music blends jazz with rock and folk influences, brought to life by a powerful six-piece band. Their debut album, recorded with a string quartet and featuring guests Anatole Muster, Emma Rawicz, and Immy Churchill, launched at a sold-out Pizza Express Soho in London on June 24th, 2024, on Zennez Records. The band has performed at major London jazz venues including Jazz Cafe and Pizza Express, and toured through the UK with their debut album.
★★★★ ‘While debut albums may be daunting, this sounds as if they have been performing together for decades.’ – All About Jazz (2024)
In January 2025, KRSIX released the “Live in London” EP, with a launch show at the Vortex. All music is written and arranged by Kasper, who draws inspiration from his observations and experiences after moving to London in 2021. Kasper performs alongside Max McLeish (trombone), Alex Lockheart (guitar), Benji Bown (piano), Jonah Evans (drums), and Toby Yapp (double bass).
