  The second-order QCD matrix elements give a very good agreement with
experimental data on the angular distributions of the four-jet events in e+e-
collisions at the Z0 resonance energy. Unfortunately the description of the
sub-jet structure is quite poor. The alternative approach, parton showers,
gives a good description of the sub-jet structure but is worse than matrix
elements when it comes to the angular distributions. Here is presented a hybrid
between the matrix elements and the parton showers that is intended to combine
the best of the two approaches.
