2018 release. Upon receiving a commissioning and residency grant from The Jazz Gallery of New York City, Filiu was able to compose his Quarteria. His goal was to create a suite of music that involved an eclectic range of musical styles performed by a diverse group of musicians. In composing, Filiu utilized a number of methods, including writing by transcribing piano improvisations, playing his saxophone, singing the melody or even without the influence of an instrument, putting his thoughts straight to paper. Through the entire process, Filiu made sure that the pieces served improvisation.
