KATATONIC SILENTIO is the latest solo moniker of Mariachiara. Active as a DJ since 2006 with several projects, she's a sound artist, live performer and independent researcher based in Milan. In 2019 she releases her first solo EP Emotional Gun, exploring the fields of experimental music, IDM, downtempo and d’n’b with a unique approach to sound design and production. 

In 2020 she joins the label and collective Bristol NormCore, on which she releases Prisoner of the Self LP. In 2021 she joins Munich-based label Ilian Tape with the EP Tabula Rasa.
Other original productions and remixes can be found on ArteTetra, Communion, Haunter Records, Biodiversità Records, Beat Machine Records, Mother's Finest, Blame Rec, Cyberspeak Music and One Instrument label.

She is an occasional curator of the monthly Normcore Attitude show on Noods Radio, and she hosts her own show Expanded Radio Research Unit  every month on Radio Raheem: an independent radio art platform for innovative works at the intersection of music, spoken word, performance and sound to challenge the limits of broadcasting; a laboratory which considers radio as an art form and a practice of experimentation and creation of multiple sonic possibilities and imaginary spaces. The aim is also to interconnect different cultural and spatial spheres and to explore the techno-sociological nature of radio, alongside its heterogeneous practices of artistic production.

In addition to pursuing a career as a DJ and specializing in music production techniques and sound design, Mariachiara is also active as an independent researcher: her practices converge halfway between sound and performing arts, new technologies and body studies, with a focus on the fields of sound design applied to performing and digital arts, sonifications and installations. Her keen curiosity for cultural studies - in particular subcultures - combined with a strong passion for music led her to approach the world of sounds with a sociological and anthropological eye, viewing it as a critical device and indicator of society and its changes – as demonstrated with her Bachelor thesis in Radio Communication: Radio Between Underground And Mainstream: Ethnographic Analysis Of Musical Programming.
