At the age of eight, Osmany started his formal education in classical piano at the Olga Alonso School of Vocational Arts in Santa Clara, Cuba. He continued these studies at the esteemed National School of Music in Havana and graduated with honors in 1991. Throughout the time that he was studying the classics, he continued to listen to as many jazz recordings as possible in order to incorporate that style into his playing.
While still in school Osmany played with many groups in Cuba including the charanga group Orquesta America. This group provided him with his first tour outside of Cuba when they went to Venezuela. After graduation he joined the jazz group of Bobby Carcasses and later the charanga group Orquesta Enrique Jorrin. These three groups gave him an invaluable education in Cuban music, jazz, and performance. After moving to Mexico in 1992, he played with various artists and groups including Israel "Cachao" Lopez, Jerry Gonzalez, Celio Gonzalez, Diego alias "El Cigala", and "Patato" Valdes, Fellove Valdes among others.

He also appeared on a number Mexican television shows performing with his group Menduvia, Antonio Sanchez, the Art 01 big band, and Celio González.
