A lowercase meeting of strings, objects, microphones and computer between core Creative Sources members Ernesto Rodrigues on viola and Guilherme Rodrigues on cello, and Karne Decorne (objects) and Simon Proffitt (microphones & computer), investigating microsound in four unhurried conversations that include moments of odd interjections, tones, and timbre.
