GRIO combines the Compagnie Imprial bass-drums rhythm section with a 5-instrument horn section: 2 trumpets, trombone, 2 saxophones. Just like a hand with its 5 fingers, this section also has echoes of Central African horn ensembles. This is Compagnie Impriales way of pursuing their exploration of African traditions, which began with Imprial Pulsar when they travelled to Mali and Burkina Faso.Inspired by the Central African Banda Linda horn ensembles and the libertarian jazz of the 60s, GRIO is writing new material, opening up new playing fields and new sonorities driven by collective improvisation.
