Cormac is a DJ and curator from Northern Ireland who built his name at seminal London clubs including Trade, Nag Nag Nag, and Bugged Out in the early 2000s before establishing himself as a regular at Berlin's Panorama Bar and Snax, where his extended closing sets span up to eleven hours. His sound blends HI-NRG, Italo house, and techno drawn from two decades of record collecting and selection. In 2021 he founded Polari Records, an imprint featuring releases alongside art from LGBTQ+ artists; he has also appeared on Ostgut-Ton. Beyond DJing and production, Cormac has hosted a BBC Radio 1 Essential Mix and launched the podcast Queerly Beloved in 2024, interviewing queer artists and allies about identity and music.
