Where this applies
London, United Kingdom. The collective agreement between West End theatre producers and the musicians' union says instruments and devices incorporating pre-recorded sounds or providing sounds by electronic means can be used provided that they do not replace or reduce the engagement of conventional instrumentalists where such players may reasonably be expected to be used, and requires the union's consent for recorded music beyond set limits. Made on 2 October 2023 and running to October 2026. West End theatres only; it says nothing about demand for live music elsewhere or about AI by name.
What this means
In West End theatres, recorded or electronic sound may not stand in for live players a show would normally hire.
What it does not yet show
One city's theatre agreement, renewed every few years.
