The term refers to two different but related styles: the first pioneered and largely practiced in North America with a harder sound similar to speed metal, and a later more widespread and popular style based in Europe (especially Germany, Italy, Scandinavia), Brazil and Japan (early Visual Kei bands) with a lighter, more melodic sound and frequent use of keyboards.
