Artist Haroon Mirza creates installations that test the interplay and friction between sound and light waves and electric current. He describes his role as a composer, manipulating electricity to make it dance to a different tune and calling on instruments as varied as household electronics, vinyl and turntables, LEDs, furniture, video footage and existing artworks to behave differently. We discuss how he’s approached our open brief to create a one-off Rega turntable for our Planar 1/1 show this year.
