The album Se hace saber (Let it be known) by the Valencian horn player María Rubio shows off the modern instrument in it's purest essence without forgetting it's history, displaying the huge range of sonorous and artistic options that it has to offer solo or together with rather unconventional colleagues. All in all, a very Mediterranean contemporary portrait of the horn in the XXI century through the visions of eight national and international composers. With this eclectic selection of works and creators, María Rubio shows us in this album her engagement with today's creation, especially that connected to her region of origin. At the same time, the recording Se hace saber has become a tribute to her technical skills, her virtuosity and her versatility, as well as the own trajectory as a horn player. Nine works of very different aesthetics which show off the intrinsic characteristics, history and the multiple facets of this fascinating and, still very unknown instrument.
