The composer Michel Portal also plays the clarinet, the saxophone and the small accordion or bandonion. A musician whom it is difficult to classify because he offers so much across a range of categories. In the field of European jazz, Portal has a profound influence. Whether he is playing as a duet with Bernard Lubat or Martial Solal ; invited to accompany groups (Humair-Jeanneau-Texier; Kühn-Humair-Jenny Clark) or playing as temporary partner with Jack deJohnette, Dave Liebman, Howard Johnson, John Surman, or Mino Cinelu for instance, his effect is notable. He has a critical outlook on liberty, which is revealed less by expression than a form of acute sensitivity that has pushed Portal to break rules and clichés and set the music free.
