Brasswork Agency is Justin Rickles, a musician, sound engineer and event producer from Chicago now making noise in Los Angeles. His production styles span widely across different styles of electronic and acoustic music. Brasswork Agency's unique sound first drew the attention of European DJs with the release of Plastic Smile EP on the French netlabel Plex Records.

Justin Rickles' career as an electronic musician began when he started DJing and producing music in Buzz Tracker and Reaktor under the name Sinuous from 1996-2004. He released vinyl on Dark Techno Records and High Octane Recordings and DJed constantly in the U.S. art gallery and rave scene. Then in 2005 Justin returned to the US after spending time in Berlin and he released For All the Wrong Reasons as the debut for Brasswork Agency. He dwelled in the world of IDM and obscure techno with his releases on (o)ndo;music, M3rck Records and his own Auxprocess Netlabel until he released the four thick minimal techno tracks of Plastic Smile EP on Plex Records in 2006. Plex then went on to release the Plastic Smile Remix EP in 2007.

In March 2008 - while on hiatus as tour manager and sound engineer for a rock band during the entire year - Lefthouse Recordings published Brasswork Agency's ambient tech-house release, Hollywood Rain EP. And at last, July 2009 marked his follow-up release, I Blend With Oceans EP, on Woody McBride's Communique Records.

As of January 2009 Brasswork Agency is the sound engineer supervisor for the premier club nights at Avalon Hollywood, which boasts the world-famous custom-built Avalon Series speaker system.
