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 the agents 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. TOA often remixes other producers' tracks and they still occasionally record for other labels such as Mokum, Hong Kong Violence and Enzyme, but their main focus for the foreseeable future is on Genosha.
