She went on to perform Rodrigo's Concierto in Argentina with the Bahía Blanca Symphony Orchestra , in Chile with the Chile Symphony Orchestra, and in London’s Kings Place with Newham Philharmonic.
Daniela is comfortable with music from all periods. She is particularly interested in the music of romantic composer Giulio Regondi, and has explored his language in depth over the last few years. As a result of this interest, she has just recorded a CD featuring Regondi's works, including the Etudes.
Daniela also enjoys performing music by contemporary composers written for guitar, and worked on several new pieces commissioned by the International Guitar Foundation in London, such as Graham Lynch’s “Orpheus” for guitar and orchestra, giving the first concert performance at London’s Kings Place with the Newham Philharmonic.
She has a deep understanding of the music of her native Argentina, which she plays on the CD “Invierno Porteño” with her duet partner, Argentinian guitarist Sebastian Pompilio. Daniela has won numerous performance awards and prizes across South America and Europe, including First Prize in the London International Guitar Competition (2015), Second Prize in the Heinsberg Guitar Competition and Festival in Germany (2017), and First Prize in the prestigious XXXVI Luis Sigall International Music Competition held in Viña del Mar, Chile (2009).  
Daniela combines her performing career with an equally successful teaching career. She works with
players of all ages and all levels, helping them to extend their musicality and technical competence. She recently played and gave masterclasses at the Antewerp Festival in Lier, Belgium and the Hamburger Gitarrentage in Hamburg, Germany.
