Mariachiara Troianiello, the Milan-based 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. 

An active DJ for more than 15 years, Mariachiara works at Milan’s record store Serendeepity. In recent years, she has performed internationally at numerous festivals, institutions and venues, including Positive Education, Spazio Hydro – Fondazione Pistoletto, La Triennale di Milano Teatro, Spazio Maiocchi, and Corsica Studios, among others. In 2019 she released her first solo EP ‚Emotional Gun‘, followed by an LP on Bristol-based label and collective Bristol NormCore (2020) and an EP on Munich-based label Ilian Tape (2021).  

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 an independent researcher, she is a member of the Scientific Advisory Board of USMARADIO: Interdepartmental Research Centre for Radiophonic Studies at the University of San Marino.

In her undergraduate thesis in 2015, Mariachiara looked at the different notions of radio and broadcasting between underground and mainstream and the multiple performative possibilities of the medium itself – a topic she currently puts into practice by regularly playing for web radios such as EOS or Radio Raheem. For the latter, she conceived Expanded Radio Research Unit, a radio format for innovative and experimental work intersecting electronic music, spoken word, performance and sound.
