It is hard to say what Roman Filius hometown is. Probably, the best way to explain it is that he was born in Cuba but raised in music. After graduating from the Higher Institute of Art in Havana and working as a saxophone professor at the National School of Music in the same city, Filiu joined to the well-known band Irakere, leaded by Chucho Valdes, from 1997 to 2006. In those 9 years that he spent with them, Filiu not only became an experienced and respected musician but also he got to travel around the world. In the U.S Irakere performed at the Carnegie Hall and The Chicago Symphony Hall, among other important venues of the music scene. Also, he participated in the recording of the album Babalú Ayé (1999), which was nominated to the Best Latin Jazz Album Grammy Award.
He continued playing and recording as a guest with the Chucho Valdes Quartet. Filiu played the alto sax in the piece You dont know what love is” for Chucho Valdés album New Conceptions, which won a Grammy Award later in 2004. Another important collaboration as a sideman was his work with David Murray. Filiu became Murrays Latin Big Band musical director in 3 of his albums, Now is the time (2002), Waltz Again (2005) and David Murray plays Nat King Cole in Spanish (2009). Also, Filiu has played with other important musicians as Omara Portuondo, Pablo Milanés, Issac Delgado, Michael Mossman, Roy Hargrove, Gonzalo Rubalcaba, Dafnis Prieto and the Buena Vista Social Club, among others.
