Words from the artist

César Poirier

My Syos mouthpiece gives a richness of sound, a unique homogeneity, in all ranges of the instrument!

Known as a very talented saxophonist and clarinetist, César Poirier is part of the swing jazz band The Meeting, and of Géraud Portal band “Let my children hear Mingus”. He played with Yonathan Avishai, the Amazing Keystone Big Band, Luigi Grasso Greenwich Sessions, Natalia M King, or his own sextet. He teaches both instruments in Paris and is considered one of the great figures of jazz in France right now.
