Joe Costello (also known as Woofer), is a Greek producer and beatmaker from Athens, Greece. He started producing at a young age, with his passion for hard-hitting hip-hop beats, making him a perfect match for his partner in crime, AK47, with whom he created the group Clique Glac. Their first official single was released in 2016, and after some time of preparation and singles, they released their first album called Sabotage in 2019. The duo is constantly working on new music.
