Ultramagnetic MC’s are an American hip hop group based in the Bronx, New York. Originally founded by Kool Keith in 1984, the group currently consists of Keith, Ced Gee, TR Love and Moe Love. The group’s work was associated with unorthodox sampling, polysyllabic rhymes, and bizarre lyrical imagery. The group released their debut single ‘To Give You Love’ in 1985, but it was their 1986 single ‘Ego Trippin’ that garnered them success. The record is notable for being the first to sample Melvin Bliss’ ‘Synthetic Substitution’ drum break sample, which is now one of the most sampled songs of all time. Their debut album Critical Beatdown introduced many new sampling techniques and thus became important to the golden era of sampling. After a brief hiatus, the group returned with Mercury Records to share Funk Your Head Up (1992) and The Four Horsemen (1993), which became their final album for fourteen years. During this time, Kool Keith went on to record numerous solo albums under the aliases Dr. Octagon and Dr. Doom, before Ultramagnetic MC’s reunited in 2007 to release ‘The Best Kept Secret’.
