Who is The Egyptian Lover? (or The Arabian Prince, for that matter)

We're not embarrassed to say we've never heard of the man the All Music Guide calls "one of the most innovative producers of the old-school/electro era...before Ice-T, N.W.A., and the late Eazy-E made Los Angeles famous (or infamous) for gangsta rap in the late '80s." Nope. Never heard of 'em. You?
