in 1969 making it nearly a full decade ahead of the musical style being recognized. 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. This is the only Deep Purple song that employs the double bass drum, and the video from the band shows them actually bring out the second bass as needed to play the song. While speedy, technical playing did not dominate Deep Purple's music, they clearly were the inventors of rock that was fast, technical and loud. Those characteristics would become the hallmarks of speed metal. The name of the origin song, "Speed King" would have also played a role in the genre's naming. At the very least, the band acknowledged what they were doing which was a radical departure from all prior rock music. Black Sabbath are a British heavy metal band from Birmingham, England and are often cited as one of the grandfathers of the genre. Though usually known for playing a fairly slow, sludgy tempo, "After Forever" is a very up-tempo song with a much faster pace than other songs in their catalogue. Still in certain other songs such as "Electric Funeral", "Into the Void" and "Under the Sun (Every Day Comes and Goes)" there is a section in the middle of the song that shifts away from the core music and plays a much faster pace than in the rest of the song, then returns to the original melody. There are those who believe that their song "Symptom of the Universe" from their 1975 release Sabotage album is the first true example of a speed metal song. Judas Priest are a British heavy metal band, also formed in Birmingham, England, that often played faster than most rock groups of the time and brought a more "metallic" sound to the guitars. Some songs, such as 1978's "Exciter", were groundbreaking for their sheer ferocity and speed; few, if any, bands exempting Motörhead played with the same tempo. Exciter (who took their name from the aforementioned Judas Priest
