Conrad Hoyer started developing his producer skills when he was just 13 years old (1993). At the age of 16 he was the youngest artist signed by DJ Ruffneck on his labels Gangsta Audiovisuals and Supreme Intelligence. He released under various names, but the big success had not come yet. Dj Ruffneck urged him to develop himself as an artist to prepare him for the big music bizz. So he enrolled at HKU Music Technology in Utrecht.

In 2001 Conrad signed a new contract at Enzyme Records, after Ruffneck wanted to go in a new direction musicwise and killed off the previous labels. This is where he created the Blackbox release as part of the Enzyme X label (also as cd release on Enzyme Records) which got great response in the underground scene. It was not until 2004 when Butterfly VIP hit the stores when his big breakthrough came to be. Recognised at big parties like Masters of Hardcore and Thunderdome. From this day on Ophidian became a name to be reckoned with. By combining the hard and raw with beautiful melody lines, he has had a huge influence on the hardcore scene of today.

In summer 2005, Ophidian founded the label Meta4, in collaboration with DJ Ruffneck and [l144934]. Since 2008 he manages it independently.

In 2019 Ophidian explained on Facebook that he left Enzyme Records, and will release his music as a free agent, for the time being. Shortly after, his release on Heresy was released, which was followed by a release on PRSPCT (as Meander). At the end of 2020, Ophidian announced he signed with Thunderdome Music. In 2021 he released his album Call Of The Void in the same label. In 2022 Ophidian presented his new alias 10 CLS, releasing an album called RUN_. Most of these tracks were made during the creation of his album on Thunderdome Music, but don’t really fit into the (mainstream) hardcore style. This album was released on Advancing Mechanism, his personal label.

In 2024 Conrad announced on Instagram, he will be taking a broader and more creative approach to the genre, making darker and slower music, influenced by Oldschool hardcore, rave, techno and industrial. Or in his own words; Effective immediately, my focus will be on producing slower, downtempo Hardcore and Industrial sound, similar to that of my first two albums, the Blackbox and Betrayed By Daylight, as wel as the Hard Techno style I released on the Protocast label - all with a modern twist.
