Sex Machineguns are a Japanese heavy metal band formed in 1996. They released their first commercial single and album in 1998.
They play a very bass-heavy form of metal, similar to what is often called heavy metal (which is how they refer to themselves), Sex Machineguns songs tend to be filled with extremely fast guitar and bass solos, which is unlike most Heavy Metal, brings them closer to the realm of speed metal. The band rides an image of being "Shock Rockers" by wearing crazy, exotic outfits often seen with visual kei bands, singing about blowing up restaurants (see the song "FamiResuBombaa") and naming one of their live DVDs "SM Show" in a very intentional allusion to BDSM. Casting themselves as shock rockers is not the prime selling point of their music though, as they also exhibit their technical skill on their instruments.

Additional Information: The band has split up for the second time. They have reformed with two new members in 2007.
