Slapshock is one of the premier rapmetal bands of the Philippines. The band was signed in 1998, when rapmetal acts were being signed left and right by the major recording companies. Six years into the business, it can be safely said that Slapshock is no flash in the pan. To date, they are the only band amongst those signed during that particular genre's boom that is still visible and active. While most acts have gone back to the “underground,” Slapshock now has four major albums to their name.

Whilst the band entered the business playing rapmetal, the members are influenced by a lot of rock sub-genres: Grunge, Metal, and glam, to name a few. It is upon hearing Rage Against the Machine that all the members of Slapshock all connected at the same time and decided that yes, they want to do something as prolific as Rage.
