The random matrices we consider have bounded entries which are independent, up to a possible self-adjointness constraint. Our results are based on an isoperimetric inequality for product spaces due to Talagrand.15 pages; AMS-LaTeX; updated one referenceProbabilityMathematical PhysicsFunctional Analysis15A52; 15A18, 15A60, 60F10text
