is an American band from Detroit, Michigan, formed in 1998 by married couple[1] Nicola Kuperus and Adam Lee Miller.

Initially, the band members were uncredited and not publicized, but by the time Anxiety Always was released, Adult was listed as husband-and-wife team Adam Lee Miller and Nicola Kuperus.

Adult have remixed other artists, most notably Felix da Housecat, Fischerspooner, Ladytron, A Number of Names, The Faint, Erase Errata and Bis.

Kuperus (who is also responsible for Adult's album artwork and photography) has sung on the recordings of other electronic acts including Death in Vegas, Swayzak and Chicks On Speed.

In 2013, the art museum Mattress Factory in Pittsburgh invited Adult to contribute an installation; the result was called Diptyching[5] which included audio, video, and the re-creation of a life size façade of a house.
