The Ultramagnetic MCs are a hip-hop group made up of Kool Keith, Ced Gee, TR Love and Moe Love. Tim Dog became an unofficial member in 1989. A former member, Rooney Roon was fired following an assault arrest. Beatbox legend Rahzel was also involved with the group early in their career. Their work was associated with unorthodox sampling, polysyllabic rhymes, and bizarre lyrical imagery. The group formed in 1984. Their first single was 1985's "To Give You Love" on the Diamond International label. Their worldwide buzz started with Ego Trippin', their first 12" single on Next Plateau Records in 1986 which was the first rap song to feature the infamous "Synthetic Substitution" drum break sample. The song is still considered a Hip Hop classic. Their next single was "Funky/Mentally Mad", one of the most sought after 12" singles of their career. Funky was based on a Joe Cocker piano sample later used as the basis for Dr. Dre and Tupac's California Love. It was released in 1987. This led to the release of their first album.
