Nik Bärtsch's Ronin is a Swiss jazz-Band from Zurich. It was founded in 2001 by the Swiss pianist, composer and producer Nik Bärtsch (born 1971). All Ronin releases are part of Nik Baertsch's RITUAL GROOVE MUSIC cycle, which combines various musical styles from funk, new classical music to elements of Japanese ritual music. The insistent rhythms also suggest the minimalism of Steve Reich. Bärtsch has called their style "Zen-Funk".
