Always influenced by various musical genres he found in Portuguese Guitar how to express his sonorous feelings. 
 Since the first hearing of Carlos Paredes songs, the sound of this instrument showed him the musical path to follow.
 Although mostly dedicated to accompany Fado, he sees in Portuguese Guitar an enormous capacity as a solo instrument, playing both the Lisbon Guitar and the Coimbra Guitar. 
He recorded in the year 2014 his first instrumental Portuguese Guitar album called “Ricardo J. Martins”, essentially made of adaptations of themes outside the musical environment of Portuguese Guitar and versions of typical songs of the instrument with own arrangements. From this CD came out the single “Danças na Eira”.

Constantly in search of new ways to the instrument, composing and playing, but always without forgetting the roots he edited in 2017 the successor album with the name “Cantos e Lamentos”.

This work counts with several special participations of musicians and instruments outside the Fado, as it is the case of the recorder, accordion, lyrical voice and percussions, as well as different musical experiences, giving to this work a unique personal stamp that goes from the music Traditional Portuguese music to classical music. 
He presented his music in the most different countries: Portugal, Spain, France, Belgium, Holland, Luxembourg, Serbia, England, Germany, Canada, United States of America, China, Ukraine, India, Venezuela, Kenya and Cape Verde.
