There have been many talks at this meeting concerning the Color Glass Condensate[1]-[5] and the Glasma[6]-[13], so I will not present an extended review the subject in this talk. I will concentrate here on providing a simplified description of the evolution of the Glasma. The Glasma is a strongly interacting Quark Gluon Plasma. It is not thermalized. It is produced very shortly after the collision of two nuclei, thought of as sheets of Color Glass Condensate, and evolves into the Thermalized Quark Gluon Plasma. The Glasma is strongly interacting because the gluon distributions are over occupied, and this overoccupation enhances the interaction strength due to Bose coherence. There may or may not be a Bose condensate of gluons in the Glasma, but this interesting feature will not be the subject of this talk[14]-[22]. In fact, I will ignore the possibility of such condensation when I analyze the Glasma, although the result I present may be generalized to the case where condensation is present.
