KRS-One is one of the legends of hip-hop, but before the fame, he was a teenage runaway who ended up in a homeless shelter. That became the source of his rap name and the place where he met his partner DJ Scott La Rock. Scott was a counselor at one of the shelters KRS stayed at. They talked about hip-hop, formed a duo that rewrote hip-hop history, and lifted KRS out of homelessness.
