The Color Glass Condensate (CGC) formalism with event-by-event fluctuations in the transverse plane, when coupled to viscous relativistic hydrodynamics (e.g. IP Glasma+MUSIC), has led to excellent quantitative agreement with a large number of data sets from high energy nuclear collisions. Recently, some of us have worked out analytic expressions for event-averaged quantities in the CGC formalism based on a near field approximation [Phys. Rev. C 92, 064912 (2015)]. Unlike numerical solutions, the analytic approach provides an intuitive picture of the classical gluon field, and its energy momentum tensor, at the earliest times (tau < 1/Qs). Here we use our previous work as the basis for the construction of an event generator that can provide a dynamical evolution of the system at early times. We calculate the time-evolution of the field strength tensor and the energy momentum tensor event-by-event in full SU(3). Using the previously established analytic methods makes the event generator fast and well controlled. It also makes it easy to single out non-abelian effects in the time evolution and to study them separately. We discuss our method step-by-step and show first results.
