On a recent visit to a friend’s new apartment here in Lisbon whilst he was framing some posters for his new pad, this was one of them. A print featuring the history of electronic music mapped out to the circuit board of a theremin, which is widely regarded as one of the first electronic musical instruments. It celebrates over 200 inventors, innovators, artists, composers and musicians who have been pivotal to the evolution of electronic music from the invention of the earliest known sound recording device in 1857 to the present day.
