MC 900 Ft. Jesus' music is influenced by hip-hop, incorporating many sound samples. His first album, Hell With the Lid Off included the single "Truth is Out of Style" which gained a cult following. His subsequent single, "The City Sleeps", explored the mind of a serial arsonist.
He released his last album, One Step Ahead of the Spider, in 1994; it contained the single "If I Only Had a Brain", which became his best-known song. The song gained increased exposure from the music video directed for it by Spike Jonze, as well as exposure on MTV's Beavis and Butt-Head cartoon show.
