Raised in Humboldt County, California, Callous attended UC Santa Barbara where he utilized his background in poetry and prose to create his first songs. Collaborating with Kush, a fellow student and rapper also from Humboldt, Callous began recording as a member of the Dirty Rats.
While still in college, Callous worked on various projects and performed in and around Santa Barbara.
After graduating in 2005, Callous returned to Humboldt where he focused solely on recording and performing with the Dirty Rats. Founded by Sonny Wong, the group quickly became well-known in the local hip-hop scene, opening for acts such as KRS-ONE, Cypress Hill, Redman, Guru, and Too Short.

In 2009 the Dirty Rats released another crew album called "Kill The Dead Horse." Dirty Rat producer GMG released his CD "Lord of the Bings" featuring the entire crew in 2010.
