Abstract
We observe that standard chiral random matrix models (ChRMM) follow fr om the constant mode sector of the Nambu-Jona-Lasinio (NJL) models whe ther in vacuum or matter. The ensuing thermodynamics is that of consti tuent quarks, with mean-field universality in general. For two and thr ee flavors new ChRMM with U-A(1) breaking are suggested. For three fla vors a first order transition is noted, The relevance of some of the r esults to lattice simulations in matter is discussed.
