Unrealtime is an audio visual software interface designed for improvisers. Developed by a team of musicians over ten years led by improviser and composer Panos Ghikas, Unrealtime is partly an aesthetic approach to improvising, partly a provocative musical partner and partly a digital prosthetic, extending existing instrumental capabilities.For this performance, the Unrealtime players will collaborate with members of the Free Range Orchestra, including poet Kat Peddie, as well as inviting the audience to play.
