David McCleary Sheldon has a dangerous mind. Abhorring the shallow trappings of make-sum-noize hip-hop, Sheldon -- Mac Lethal to y'all -- spews smart, caustic, bleak, hilarious, slang-and-cliche-free verse with the inspiration and artfulness of a poet but the attitude of a reform-school dropout. At past nationwide Scribble Jam freestyle competitions, Mac's whip-fast wit has left big-chested MCs dumbstruck. And his writing has grabbed the attention of flagship underground rap label Rhymesayers, which is set to issue Mac's first national release early next year. Having heard early mixes, we'll be the first to announce that 11:11 is worthy of purchase, praise and repeated rotation. Hell, if it catches the proper hype, it could even change the state of hip-hop as we know it -- not because of the sounds (ably produced by Nezbeat and Been) but simply because of what Mac is saying, which is exactly what needs to be said in pop music today. But to hear what that is, you'll just have to wait.
