  The electromagnetic emissivity from QCD media away from equilibrium is
studied in the framework of closed time path thermal field theory. For the
dilepton rate a nonequilibrium mesonic medium is considered applying finite
temperature perturbation theory for $\pi -\rho$ interactions. The dilepton rate
is derived up to the order $g_\rho^2$. For hard photon production a quark gluon
plasma is assumed and calculations are performed in leading order in the strong
coupling constant. These examples are chosen in order to investigate the role
of possible pinch terms in boson and in fermion propagators, respectively. The
implications of the results for phenomenology are also discussed.
