Remember that moment when your walkman turned into a noise-making effect for any tape you’d feed to it? Ei Wada too. The Japanese former programmer adopted a quirky musical career after attending a gamelan performance, which inspired him to reproduce the eerie sounds using electronic waste.

His music illuminates the unearthly beauty of outdated technology we tend to throw away. If that makes you feel #nostalgic, here’s a pocket synth to go and play with.
