The album was mastered by Yann Faussurier of Iszoloscope, containing remixes by Antigen Shift, Tonikom, and Synapscape.  and received generally positive reviews.
In 2009, Khan released a second album, A Bright Cut Across Velvet Sky.
Ad·ver·sary performed at the 2012 Kinetik Festival, ending his set by screening a video, We Deserve Better, which criticized headlining acts Combichrist and Nachtmahr and the industrial music genre in general, and, according to the website IdieYoudie, "openly critiques ... the use of misogynist and racist tropes in those bands' music and publicity materials".
