Rapcore

Rapcore is a fusion genre of hip hop and punk rock or hardcore punk. Beastie Boys, formerly a hardcore punk group, began working in the hip hop genre. Their debut album, Licensed to Ill, largely featured a rock-based sound. Biohazard is considered to be a strong influence on the genre's development. Huntington Beach-based punk band Hed PE performs a fusion of styles ranging from hip hop and reggae to punk rock, hardcore punk and heavy metal. Although they are considered to be performers in the rapcore genre, they refer to their musical style as "G-punk". Kottonmouth Kings perform a style which they refer to as "psychedelic hip-hop punk rock". Three of the earliest formative rapcore bands were 311, Rage Against the Machine, and Every Day Life. Professional critic Mark Allan Powell considers the rap rock song "Jesus Freak" by DC Talk, which was marginalized by many critics due to its Christian lyrical content, the turning point of when the popularity of grunge gave way to rapcore.

Among the first wave of bands to gain mainstream success were 311, Bloodhound Gang and Limp Bizkit. Although the popularity of rapcore declined, some believe that rapcore may regain popularity, with younger music fans discovering bands in the genre. Drew Simollardes of the rapcore band Reveille states that "I feel like lately it’s more appropriate. People are sick of a lot of the stuff that’s out there right now."
