catHead – Heledd C Evans – Joshua Jones, Jim Gibson & Howl Hubbard – Orchestre Tout Puissant Marcel Duchamp – Yakkida! – Ivor Woods

catHead is a new electronic music project working across genres, most notably blending elements of ambient, electroacoustic, techno, downtempo, breakbeat and UK bass. catHead designs and builds their own experimental instruments from recycled materials and uses them alongside vocals, environmental recordings and a variety of hardware, traditional acoustic and electronic instruments. Producing ethereal soundscapes, pulsating bass rhythms and glistening textures punctuated by natural sounds and metallic drum hits, catHead’s music evokes a warm sense of nostalgia whilst also hinting towards an eerie dystopian future. The new project is set to launch in 2023 alongside a series of live performances.

catHead is the alias of Gwen Siôn, an award-winning composer, producer, pianist and multidisciplinary artist working with sound, sculpture, DIY electronics, moving image and installation. She creates multi-instrumental, vocal and electronic compositions, and makes her own hand-built instruments and sculptural sound devices by repurposing both natural and industrial materials.

Gwen is interested in exploring ways of interpreting landscape in musical terms and the relationship between sound and environment, ecology, mythology, ritual and synaesthetic crossover. She has worked on a broad range of music and sound projects, commissions, public installations, performances, exhibitions and residencies throughout the UK and internationally, having gained support from organisations such as Arts Council England, Arts Foundation, Sound and Music, British Music Collection, PRS Foundation, Sound UK, Ty Cerdd, Wales Millennium Centre, Jerwood Arts, Oxford Contemporary Music, Atelier11 Paris, Greywood Arts Ireland, StokkoyArt Norway, University of the Arts London, Netflix, Leland Music, Sustainability First, BBC and Liquid Listening. Gwen’s music won the 2021 LMVH (Moët Hennessy Louis Vuitton) X Central Saint Martins ‘Maison/0 This Earth Award’ (a prize championing sustainable arts practice and works that advocate for nature), was nominated and subsequently shortlisted for the 2021 ‘MullenLowe NOVA Awards’ and was also shortlisted for the 2021 ‘Sustainability First Art Prize’. Last year Netflix and Leland Music selected Gwen to take part in a composer mentee development programme supporting two emerging composers to gain an insight into composing for film and TV during the production of the latest Top Boy season, receiving advice and mentorship from the series original score composers Mikey J Asante and Brian Eno as well as the Leland Music team and Netflix UK music department. Gwen was also nominated for the 2023 Electronic Music Award as part of the Arts Foundation Futures Awards, she was subsequently shortlisted and made one of only four finalists across the UK for the category. Funding awarded by Sound and Music’s New Voices programme and the Arts Council England DYCP grant has supported the development of a new experimental electronic music alias – catHead, as a result Gwen is undertaking a tour of live performances to launch the project taking place between August and December 2023.
