"Letters that are numbers and numbers that are letters. Melodies that are rhythms and rhythms that are melodies. Diogo Graça, son of Lisbon, and as such, is deeply rooted in the melancholy of the Portuguese being and seeks emotion in the music that dances. A pure Dj, Diogo, searches in the past and present for the music of tomorrow, without prejudice, ethnicity or style for the simple purpose of opening the doors of discovery. "XCI" in Roman numerals is "91", a number that marks his "origin", the year of his birth and where it all began."
