<div>Abstract:</div>
<span>The thermodynamic behavior of QCD at large N (where N is the number of colors) is interesting for many reasons. In the hadronic domain, the thermodynamics is tied directly to spectroscopy. The subject is quite old; it has been studied for decades. Despite
this, there are a number of features that are not widely appreciated and are quite surprising. In this talk a few of these are noted given the assumption that QCD has a generic first-order phase transition at large N as one sees for pure gauge theory. The
existence of a first-order transition implies metastable phases. One surprise is that under this assumption large N QCD has a supercooled metastable plasma phase with negative absolute pressure---that is a pressure below that of the vacuum. Another surprise
concerns the region beyond the endpoint of the superheated hadronic which, at large N--rather than curving as one expects in an unstable region--is flat.</span>
