He signed on this label under three different aliases: ks, Deme, and Larren Klark.

In 2003 he released an IDM EP called "Teirce" on Enough Records. Since then he's been preparing a new side project, unrevealed to this date.

His work, as well as the entire Nashmeja material, is available throught the Scene.org and OpenBSD archive repositories.
