Fantini Futuro (2019) is an electronic opera by Ben Neill for the Mutantrumpet, countertenor, Baroque keyboards, and interactive video projections. The immersive piece is based on the music and life of early Baroque trumpeter/composer Girolamo Fantini, who was responsible for bringing the trumpet indoors from the hunt and the battlefield to the realm of art music. Using an array of interactive technologies, Fantini is depicted as a traveler through space and time by a synthesis of early music, minimalism, and digital media performance. Fantini’s translocation of the trumpet is mirrored and reimagined by Neill’s Mutantrumpet, which extends the acoustic instrument into the virtual realm.
