The Freiburg Diptych by James Dillon is a contemporary work for Solo Violin, Tape and Live Electronics. The two parts of the diptych are balanced around certain polarities between reality and illusion such as analogue/digital or live/recorded. The work was commissioned by Musik des Jahrhunderte, Stuttgart and Huddersfield Contemporary Music Festival and was first performed by Irvine Arditti and the SWR Experimental Studio at the Eclat Festival, Stuttgart on 9 February 2020.
