Nu-disco is a 21st century dance music genre associated with a renewed interest in 1970s and early 1980s disco, mid-1980s Italo disco, and the synthesizer-heavy Eurodisco aesthetics. It often associated it with re-edits of original-era disco music, as well as with music from European producers who make dance music inspired by original-era American disco, electro and other genres popular in the late ′70s and early ′80s. It is also used to describe the music on several American labels that were previously associated with the genres electroclash and deep house. See Wikipedia for more info on nu-disco music.
