Mariachiara Troianiello, the Italian sound artist behind the moniker Katatonic Silentio, works at the crossroads of electronic music, performing arts and sound studies. Both as a live performer and an independent researcher, she seeks to bridge different spheres and approaches to sonic production. ​ Active as a DJ for more than 15 years, her sets adopt multiple forms, fluctuating between an analogue past and a technological, fast-paced future. At times, her sets focus on pure abstraction, consisting of ethereal soundscapes that seek to transcend the tangible through a mix of musique concrète, world, spoken word, ambient or dub. At others, they come across as concrete and club-oriented, crossing techno, broken beats or drum'n'bass.

Mariachiara views sound as a critical tool and has a genuine interest in exploring sonic possibilities and practices from both artistic and sociological perspectives.

​As a composer, she explores the interplay between sound, space, movement, and the body through her work in theatre and dance. As a researcher, her current work delves into the more ancient and mythological dimensions of sound, exploring the origins of sound itself and tracing its evolution from primitive cultures to the modern world.
