The quintet Pilgrim, founded by Zurich-based tenor saxophonist Christoph Irniger, has over the years become one of the most exciting ensembles in young European jazz. They present their fourth recording, Crosswinds, in which there is a certain ambiguity. “Some compositions are freely improvised, while others are completely notated, yet most lie in between, with an elasticity that reflects a life of freedom, where informed choices are made spontaneously.” The group was formed in 2010 with five members: Christoph Irniger, tenor sax; Stefan Aeby, piano; Dave Gisler, guitar; Raffaele Bossard, bass; and Michi Stulz, drums.
