Son of veteran film composer and singer Gangai Amaran, he often composes rap songs in Tamil cinema and is known for his comical performances in his elder brother Venkat Prabhu's films Chennai 600028, Saroja, Goa and Mankatha. His stage name, Premgi, is actually a spelling error, as it is meant to be "Prem G.", (the G referring to his father's name).
Premgi is the son of veteran director and musician Gangai Amaran, and the younger brother of film director and actor Venkat Prabhu. Film composer Ilaiyaraaja is his uncle, while Yuvan Shankar Raja, Karthik Raja and Bhavatharini are his cousins.
