Roots of Keith Murray

EPMD is an American hip hop duo from Brentwood, New York. The duo's name is an initialism for "Erick and Parrish Making Dollars", referring to its members: emcees Erick Sermon and Parrish Smith. During an interview on college radio station WHOV in 1987, Parrish Smith stated that the name evolved from the original: "We were originally known as "EEPMD", but chose to go with EPMD because it was easier to say." He also stated that they dropped the two "E's" because N.W.A's Eric Wright was already using "Eazy-E" as his stage name. The group has been active for 39 years.
