Ho99o9 (pronounced Horror) is an American hip hop group founded by theOGM and Eaddy in 2012 in Newark, New Jersey. They relocated to Los Angeles in 2014, where they attracted a strong cult following on account of their live performance, according to the LA Weekly, and attracted collaborators such as Ian Longwell who plays drums and produces for Santigold. In 2016, the group brought former Black Flag member Brandon Pertzborn into the band as their drummer. Their style combines dark hip hop with the aggression of hardcore punk.
