Back in April, Mauricio Valdés introduced himself through email. I am so glad he did. In addition to making interesting music, he is in the process of developing software, Arenero, that should be of interest to many modern guitarists. According to Valdés, “Arenero is a free software system for improvisation, dedicated to guided improvisations for musicians and aficionados of sound art. It has been used as the basis of sessions for many different groups working in free improv workshops and conferences in Mexico and Europe.” For more info on Arenero and Valdés, read on.
