Regarded as one of the best Filipino rappers of all time, his fast-flowing vocal style has made him one of the best-selling and most successful hip-hop artists in the Philippines. He was described by fellow Filipino rapper Francis Magalona as "a blacksmith of words and letters, and a true Filipino poet."

He is referred to as a trailblazer and the long-standing giant of the Pinoy Hip-Hop scene. In a career spanning 25 years, Gloc-9 has won over 60 awards including the prestigious 'Sudi National Music Award' by the National Commission of Culture and Art.
