Silvestre Pestana's work is imposed by the radical nature of the interventions that, since the first moment, rest on an intentional hybridity resulting in the game and permutation between linguistic and not linguistic signs. The contamination that, in the 60's and 70's, derives from the use of different graphic material, will find, in the 80's, support in the use of video and computer media. At this level, it can be said that his poetry for computer programming opened new routes to experimental poetry. Frequently mixing, intentionally, issues related to materiality and mediation, in his work procedures based on digital systems appear mixed with the analog character representation. His recent work, in the context of performance, in real or virtual spaces as Second Life, are essential to assess how the experimentalist practices interfere with the social practices in which they articulate.
