Based in Montreal, Canada, the Improvisation Workshop Project (IWP) brings together musicians of all backgrounds and experience levels (students and professional musicians, jazz and classical) to explore the tradition of jazz as “improvised chamber music” based on collective improvisation. Weekly playing sessions assemble different casts of musicians to try new ideas and interpret new material brought by project lead Jean-Michel Pilc and other participants. Using an “improvisation as instant composition” approach and the collective improvisational process, the IWP investigates how such diverse disciplines as composition, orchestration, musical interpretation and improvisation combine organically into a coherent whole in jazz music, and also how a diverse lineup of musicians can hold natural and meaningful musical conversations.
