    "Obsidia – dos sons invisíveis ou das imagens audiveís" – 09:14 (2017), Tape Music, Stereo, 48kHz, 24 bit 

    ("Obsidia – of the invisible sounds or of the audible images") _ Commissioned by the Música Viva Festival, premiered at the 23rd edition of the festival, on May 26th 2017. 

    One of the connotations of the term / verb “obsidiar” (to obsess) is the idea of obsessive pursuit, of insistent focus.

    This idea of insistence is musically employed in the sense of the exploration of sound aspects that, throughout the piece, are heard. One of these aspects is the repeated focus on the spectral degradation of sounds, that is, the detailed work of subtraction, addition, multiplication, etc., of spectra of various sonic families. 

    Another aspect that qualifies this piece is that, in terms of compositional methodology, it focuses on quasi-granular timbrical exploration, making extensive use of the doppler effect, animating sound objects with pronounced gestures and movements. 

    The sonic sources of this composition consist in sounds recorded from various objects, manipulated and recorded at the ORF (Austrian Broadcasting Corporation) studios in Vienna, Austria, on the occasion of João Castro Pinto's radio art piece: "The No Land Soundscape Project", on April 30th 2017 (more info @ http://kunstradio.at/2017A/30_04_17en.html ), and sounds of machinery dedicated to the printing of paper, banknotes and currency / coinage at the Imprensa Nacional Casa da Moeda, in Lisbon, Portugal.
