I will discuss eikonalized parton-parton scattering through singular and classical Yang-Mills solutions in QCD. I will show that these solutions escape to Minkowski space in the form of exploding QCD sphalerons. I will use these solutions to assess semi-classically the number of prompt quarks and gluons generated in hadron-hadron collisions at high-energy and nucleus-nucleus collisions at RHIC energies. The QCD sphalerons are extremely efficient for jet quenching at RHIC through QCD synchrotron radiaton. They also provide a novel mechanism for quark production through spectral flow.
