With stripped down production, brilliant lyrics and the fiercest delivery of his career, KRS-One and company deliver the best LP in thier entire musical cannon. While many disliked and/or misunderstood this album when it first appeared, the last decade and a half have opened minds and ears to it's sheer daring and revolutionary impact. The music, as always is sliced down to the barest essentials, a simple 808 drum machine here, some reggae flavoring there (the hypnotic "Breath Control II") African Drums ("The Homeless") and even wah-wah guitar over funky drums ("Original Lyrics", my personal fave) and the production isn't too crowded allowing Parker's biting, incisive lyrics and terrific vocals plenty of breathing room and the attention they deserve. While things do get a bit preachy, the sheer enjoyment of these performances will leaven out the heavy-handed tone of the words. A rap LP was never more aptly titled. School is in session.
