The concert involves the use of electrical instruments that contribute to make this formation a source of infinite musical expression. The project started in 2012 when the first quartets started recording and since then has undergone various transformations. The members are musicians with eclectic musical interests, active in various musical fields, which perform both classical and jazz music, rock and avant-garde music. They collaborated with internationally renowned artists such as Salvatore Sciarrino, Bobby Mc Ferrin, Andrea Bocelli, Michael Nyman, Mark Isham, Paolo Fresu, Trilok Gurtu, Butch Morris, Tristan Honsinger and others. In addition to classical instruments, they use Ned Steinberger and Reiter electrical instruments, using electronic sound effects. In their music there are frequent contaminations between genres, the use of video projections and collaborations with other musicians, authors and artists that make their performances stimulating and involving.
