Over the past few years, Fidalgo has gradually exploited his own talent as arranger and composer. Working with producer Jordi Cubino, he has contributed arrangements to the fundraising album Disc de la Marató de TV3 and has served as assistant music director on the successful talent show Eufòria. As a composer, his activity has recently evolved towards a polystylism with multiple influences and in permanent synergy with other artistic disciplines such as painting, poetry or photography. His works as arranger and composer are showcased on his YouTube channel, which features the deliberate combination between the artistic and the pedagogic dimension of his compositions, in line with the spirit of classical works such as Schumann’s "Album für die Jugend" or Béla Bartók’s "Mikrokosmos".
