Lawrence "Kris" Parker, better known by his stage name KRS-One, an abbreviation of "Knowledge Reigning Supreme Over Nearly Everyone", and Teacha, is a rapper and producer. He rose to prominence as part of the hip hop group Boogie Down Productions, which he formed with DJ Scott La Rock in the mid-1980s. KRS-One is best known for his hits "Sound of da Police", "Love's Gonna Get'cha (Material Love)", and "My Philosophy". Boogie Down Productions received numerous awards and critical acclaim in their early years.
KRS-One is politically active, having started the Stop the Violence Movement. He's also a vegan activist, as expressed in songs such as "Beef":

"So just before it dies, it cries
In the slaughterhouse full of germs and flies
Off with the head, they pack it, drain it, and cart it
And there it is, in your local supermarket"

While KRS-One has turned away from traditional religions he doesn't have a naturalistic worldview. Referring to his book, The Gospel of Hip Hop, he has said: "this book will be a new religion on the earth ... I think I have the authority to approach God directly, I don't have to go through any religion..."
