Minimal wave is a contentiously named genre of electronic music which focuses on electronic, pre-MIDI (1982, but not pre-sequencer) instrumentation and themes of sincere, rather than ironic, detachment. It comprises obscure, atypical examples of genres such as new wave, so-called "minimal" electronic or synthesizer music, electropunk, synthpop, post-punk, coldwave, electroclash and electropop. Although much Minimal Wave music was created in the late 1970s and early 1980s and subsequently appeared on bootleg and one-off compilations, the genre didn't have a name until a record label of the same name began releasing compilations and reissues in the mid-2000s.
