Jazz Pianist Leopoldo Osio was born in Ciudad Bolivar, Venezuela. He started playing piano at a very early age, inspired by Venezuelan Traditional Music. He credits George Shearing as being the first musician that got him hooked on jazz when he was 14 years old. Around this time, Leo began studying with jazz musician and promoter Ivo Farfan, who introduced him to jazz trumpet player Julio Mendoza who was to become his principal mentor and develop his interest in bebop. Leo immersed himself in the music of Charlie Parker, Dizzy Gilliespie, Chucho Valdes and Paquito de Rivera. At the age of 16, he was invited to perform in the Festival de Jazz en el Orinoco with important Venezuelan musicians like Ivo Farfan, Victor Cuica, Roberto Giron, and later the same year The Jazz Festival El Hatillo with Julio Mendoza Quartet.
His interest in music led him to study at several universities in 3 countries to improve his knowledge in different areas of the music, including Jazz and Latin Music at IUDEM-Venezuela, Brazilian Music at Conservatory Souza Lima-Brazil and Newpark Music Centre where he was awarded a Bachelor of Arts in Jazz Performance (Hons) in 2010
