James has dedicated a large part of his work, especially since 2011, to solo playing and the development of a long-form work he calls Sighs Too Deep For Words. His solo work is a synthesis of the improvised and the composed and often incorporates multiple clarinets (Bb, Eb, prepared), penny whistles, ritual and singing bowls/bells, shruti box, and other ambient sound makers. He has toured with his solo project extensively, often in conjunction with workshops and masterclasses on improvisation at universities, colleges, and music schools.
