Ahmad Jamal (b.1930) is one of my favorite jazz pianist, a living legend. For years he played only in trio and only after the begining of the '80s he began to include in his group George Coleman (b.1935) the well known saxophonist, composer and bandleader of Memphis, Tennessee, with which made also different tournée in Europe.
