In 2017, Paul Purgas discovered a collection of early Indian electronic music at the National Institute for Design in Ahmedabad: the “NID Tapes”. Compiled between 1969 and 1972, the collection documents electronic works by the hitherto unknown Indian composers Gita Sarabhai, I.S. Mathur, Atul Desai, S.C. Shama and Jinraj Joshipura. They worked at the country’s first studio for electronic music, which had been established at the NID in the early years following Indian independence – a time of visionary experimentation and artistic freedom.

Together with our guests, we discuss the manifestations of electronic music in other cultural contexts and, in turn, their influence on contemporary composition.
