Of the innumerable electro-techno acts to arise from Detroit during the 1990s, Adult. may be the most unique, instantly recognizable for their starkly grim visual style as well as their anxiety-ridden music style. Adult. (note the period) is comprised of married couple Nicola Kuperus and Adam Lee Miller, who began their recording career together as Plasma Co., a name by which only an obscure 12", Modern Romantics, was released in 1998. Miller had been releasing music on his electro-techno label Ersatz Audio since 1995, beginning with his debut as Artificial Material. He also released music on Ersatz Audio as Le Car, a duo also including Ian Clark; confusingly, the two billed themselves in Le Car as Adam Equation and Ian Cinch-Jones. However, it wasn't until 1998 that Miller began releasing music produced in conjunction with Kuperus.
