La Roux (pron-enl???ru? in English, IPA-frla??ulang) are an English electropop and synthpop duo made up of singer, keyboardist, co-writer and co-producer Eleanor Jackson (born 12 March 1988), and keyboardist, co-writer and co-producer Ben Langmaid. Jackson describes their respective roles as "very much a half and half sharing situation... not like a singer producer outfit", but also recognizing that it often can "look like a solo act".

Their music is influenced by 1980s British synthpop including Yazoo (Yazoo (band)), Erasure, Depeche Mode, The Human League, Heaven 17 and Blancmange (Blancmange (band)). The bands name originates from Jacksons red hair; she has said: quoteTo me, it means "red-haired one" - and it does, vaguely. Its just a male version of "red-haired one", which I think is even cooler, because Im, well, androgynous anyway. So it kind of makes sense.
