Castellarnau’s recent works are especially influenced by the poietical researches of informalist painters reinterpreted in music from an electroacoustic morphological sound approach. Fascinated by the grotesque as a poetical source and the expressive capacity of the sound matter, Castellarnau’s work combine sound refinement and timbre complexity.
Born in Catalonia [Spain] Carlos de Castellarnau has started studying composition in 2010 with Ramon Humet and Agustín Charles in ESMUC in Barcelona, then with Stefano Gervasoni and Yan Maresz in CNSMDP in Paris in 2012-13. He has participated in the Cursus 1 and 2 in 2013-15 in the IRCAM under Hector Parra’s guidance.
His works have been awarded in several competitions such as the Joan Guinjoan Composition Competition in Barcelona, the JukkeBoxx NewMusic Award in Munich or the  International Competition “Premio Trio di Trieste”. His music has been played by ensembles like Ensemble Court-Circuit, Proxima Centauri, CrossingLines, Curious Chamber Players, Vertixe Sonora Ensemble or Neofonía Ensemble among others.
