Aristotle Pollisco (born October 18, 1977), known by his stage name Gloc-9, is a Filipino rapper, singer and songwriter. Regarded as one of the best Filipino rappers of all-time, his fast-flowing vocal style has made him one of the most successful hip-hop artists in the Philippines. He was described by fellow great Filipino rapper Francis Magalona as "a blacksmith of words and letters, and a true Filipino poet."
He has collaborated on almost a dozen songs with other OPM artists; "Lando" with the late Francis M, "Upuan" with Jaezelle, "Bagsakan" with Parokya ni Edgar , "Baon" with Gab Chee Kee of Parokya ni Edgar and Francis M, and "Sari-Saring Kwento" with Noel Cabangon and Champ Lui Pio. His songs mostly tackle social issues such as social injustices, poverty and patriotism. He began his musical career with the gangsta rap group Death Threat.
Gloc-9 is notably one of the few artists in the Philippine music scene who has won an award in every album he created.
