The origin of the genre's name is the aptly named "
Speed King" by
Deep Purple. Recording on the song started in 1969 making it nearly a full decade ahead of the musical style being recognised. The song is not only very fast and technical but was also extremely loud creating noticeable distortion in the recording process. The
title song for the band's next album,
Fireball, is a further refinement of the band's influence with drummer
Ian Paice's use of the
double bass drum. The way the double bass drum is played in "Fireball"—uptempo "
four on the floor"—became a mainstay in many heavy, speed and thrash metal songs in the years that followed. Speed metal eventually evolved into
thrash metal. However, on the very next page, Christe calls speed metal a "subset of thrash metal" and argues that "There was little intrinsic difference between speed metal and thrash metal. With the sudden boom of fast, raging bands, however, it sometimes helped to distinguish between the throbbing, rhythm-heavy thrash metal and something a bit cleaner and more melodic--dubbed speed metal." Some may argue that
first-wave black metal bands such as
Venom,
Sodom, and
Bathory were speed metal and that black metal evolved as an extreme form of speed metal. Speed metal also played a major role in formation of
power metal, with
Helloween's, one of the "big four" of power metal, first two albums being speed metal, or speed metal adjacent, in the case of
