The term "Hi-NRG" without the "Disco," was first officially mentioned in the UK music magazine Record Mirror in 1983, which championed the gay underground sound and published a weekly Hi-NRG Chart. The first ever Hi-NRG record to hit the UK's Top 100 was Hazell Dean's "Searching (I Got To Find A Man)," released on Proto Records. However, the term "Hi-NRG" was brought to mass attention by Evelyn Thomas's hit, "High Energy" (1984), produced by Ian Levine in London. This form of "Hi-NRG", is typified by an energetic staccato sequenced synthesizer sound, where the bass often takes the place of the hi-hat (alternating a more resonant note with a dampened note to signify the tempo of the record). There is also often heavy use of the clap sound found on drum machines.

    During 1984 the music began to crossover into the mainstream pop charts in the United Kingdom and the United States, largely due to the success of the Record Shack record label. It was around this time that the term "Hi-NRG" started to be used widely to describe various dance music styles related from the Disco Era, but not based on the so called "new sound", like "New Beat". The Record Shack label also enjoyed chart success with tracks by Break Machine, Miquel Brown and an unlikely comeback single by Eartha Kitt ("Where Is My Man", 1984), which proved to be a massive hit on both sides of the Atlantic.

    The British producer trio Stock Aitken Waterman, were Hi-NRG producers at the start of their careers, working with artists like Divine and Hazell Dean. Eventually, they created their own music style, called Eurobeat, which is the UK's answer to Italo Disco. Because of their previous success on the American market, all of the trio's Eurobeat productions in the mid-1980s, marketed as "Hi-NRG" in the USA, sold well, and one of them, Dead or Alive's "You Spin Me Round (Like a Record)" became the most successful Hi-NRG single ever. The song reached number one on the UK Singles chart and the Top 10 on the Billboard Hot 100 in the U.S.A.

    Stock Aiken Waterman's "Hi-NRG" version (which actually was Eurobeat), lasted around 6 years and disappeared totally around 1991. The original Hi-NRG music was largely superseded by House music by 1990 but still enjoys an underground following, usually in the form of Hi-NRG versions of mainstream pop hits.

    A second generation of Hi-NRG emerged during the 1990s, and it was a major force in the Club/Dance music world, thanks to the success of several prominent Hi-NRG artists and the Rockamerica Hi NRG - like remixes of various popular hits. A crossover of Eurodisco and Hi-NRG helped even more to remain popular on the underground American gay disco scene, with artists such as RuPaul, Kristine W, Abigail, Nicki French, Lonnie Gordon, Kym Sims and, more recently, Sean Ensign. The basic production of the 1990s sound has remained nearly the same, however, the rhythms and synths used sound different, and the overall tone is usually edgier. Finally, the latest Hi-NRG productions, place greater emphasis on vocal personality.
