"Marcos' sensitivity to the musical phrase and use of shade and color in his tone production is only shadowed at times by his unbelievable command of the instrument." Yehuda Gilad (Clarinet professor Colburn School, L.A.)
En abril de 2008 interpreté el Concierto nº1 para clarinete y banda de Oscar Navarro, con la Banda de la Sociedad Filarmónica Alteanense, en Palau Altea.
