The ‘conduction’ method invented by ‘Butch’ Morris is one of the most original ways of combining improvisation with composition in real time. It consists in series of gestures-commands used by the conductor during collective improvisation in order to give it a proper form. Before arriving in Warsaw, ‘Butch’ Morris taught a week-long workshop for the ‘Odyssey’ Orchestra, founded by Adam Kaczyński at the Academy of Music in Cracow. He had previously presented 167 versions of ‘conduction’ all over the world, many of which are already considered as 20th-century classics.
