Het Concreet Scanner 2023

"In November 2023, I joined the team at Het Concreet in Tilburg, The Netherlands for a week long residency.

Het Concreet is a Dutch sound collective dedicated to finding new sounds by experimenting with analog electronic devices, magnetic tape and acoustics. Their analogue ambitions are rooted in their studio space, where they seek to find new meanings of sound by working with techniques that have become largely obsolete in today’s world. Their main instrument is magnetic tape, so I collaborated with my own analogue gear.

Radio Concrète was a a 12-hour broadcasting marathon that explored radio as a compositional tool and included contributions from Margherita Brillada, Veerle Pennock, Clara Byom, Bas van Druten, Nele Möller, Marieke van de Ven, Sharon Stewart, and was hosted by Steph Byrne.

During my stay, I fell in love with the Elektor Formant, a vintage Dutch synth handmade by Jos van Ras. In addition I used my SOMA Ether, Lore Mill Keyed Mosstone and Make Noise Strega synth. At the end of the broadcast, I made an intimate performance for a live and dedicated audience in collaboration with Het Concreet. This is an excerpt from that show."
