Guru (born Keith Edward Elam, July 17, 1966), is an American rapper, and the lyrical half of the hip-hop group Gang Starr, together with DJ Premier. With his Jazzmatazz album series, he is also considered to be one of the pioneers of hiphop/jazz crossover. The name Guru is a backronym that stands for "Gifted Unlimited Rhymes Universal" and the less often used "God is Universal, he is the Ruler Universal". As stated in numerous interviews, he is of Trinidadian descent. Founded in 1987, Gang Starr built a sizable following in the early 90's, releasing classic albums like, Step in the Arena (1991) and Daily Operation (1992). Guru's lyrical style is based on battle rhymes delivered smoothly, modestly, and with sly wit; he typically avoids using overwhelming charisma, focusing instead on his rhyming ability. Over the years he has even taken on younger rappers, including Jeru the Damaja, as proteges. He is credited with DJ Premier for executive producing Jeru's debut, The Sun Rises in the East (1994).
