Fágner actively participated in several school plays during high school, contributing to the soundtrack as part of his literature classes. Having spent countless hours listening to soundtracks from games, films, and series, he had developed a deep familiarity with a wide range of genres and themes. For the school plays, which were primarily inspired by Brazilian literature, Fágner composed original soundtracks for three productions: Ensaio Sobre a Liberdade, Angústia, and Vidas Secas.
While in his free time, Fágner would compose a few EPs, Covers and Singles to test his skills.
