  We estimate the production of electromagnetic radiation (real and virtual
photons) from the early, pre-equilibrium, stage of relativistic heavy-ion
collisions. The parton dynamics are obtained as a solution of the Boltzmann
equation in the Fokker-Planck diffusion limit. The photon and dilepton rates
are integrated and the obtained yields are compared with those from standard
sources and with available experimental data. Non-equilibrium photon spectra
are predicted for Pb+Pb at $\sqrt{s_{\rm NN}} = 5.02$ TeV.
