Ad Libitum is the result of the musical and artistic collaboration of Carmen Fernandez and Pablo Amante. It was born when the alternative band “Beta Julieta “ splitted up. At the beginning seemed to follow the trace of what “Beta Julieta “ was, but althrough the years, the research, the experience and the studies, has become a scientific-artistic-musical research complex machine, and a musical, literary and philosophic creation project which tries to face the fast, complex and technologic world of today. Ad Libitum perceives the world in a fractal way (scale symmetry) where the micro and the macro are linked to the angle from where they are been observed, and where, in a non lineal way, every part of the whole can be in touch with another part of itself. Our music reflects our internal diversity, from the occidental and oriental culture, the folklore and the ancient music, our rock roots, the academic studies, the profound interest and the research with the music color and the sound manipulation through the technology and the electronics, to the purpose of having an impact on the audience. The integration and harmonious interaction of everything we are, receive and filtrate, becomes Ad Libitum.
