Developed between 2022 and 2023, (Des)-Vítreo / (Un)-Vitrify gradually grew into a slow-moving experiential piece for three performers, two glass plates, plexiglas, transducer speakers, microphones and light. 
The composition works with feedback -not always in its ‘pure’ state- and the resonating glass bodies, mixing both in one digital/analog instrument, which allows the musicians to manipulate different parameters of the feedback/glass sound, while still working with the unpredictability and wildness of feedback. 

It becomes thus possible to obtain the same or rather similar sound qualities and behaviours when playing, but the result of each performance will have nevertheless its small differences, playing with the liquidity between the fixed composition that it is, with anchored form, sounds and gestures, and improvisation sections.
