As true dissidents within the hardcore scene, The Outside Agency has always had its own unique sound. This was already evident on their first three releases, which they produced for Mokum Records in the late 90s. After that period hardcore suffered a drastic change in direction and the two members of TOA (DJ Hidden & Eye-D) no longer felt at home in the genre and focused their attention on drum & bass instead. Around 2001 hardcore transformed yet again, but this time they were very pleased with the direction it had taken, and they started producing and playing hardcore again with renewed vigor. After a string of successful releases on several international underground labels such as Black Monolith Records and Otaku Records the two founded their own successful imprint Genosha Recordings which is now one of the leading labels in dark underground hardcore. In 2008 the two would set up Genosha One Seven Five for their hardcore and drum & bass crossover material. A third label called Genosha Basic was set up in 2016 for acid and techno material.
