We study the influence of collisions among hard particles on the collective modes of finite-temperature QCD. In particular the important effect on the growth rate of the instable modes in an anisotropic system is discussed. This is of relevance for understanding the early thermalization of a quark gluon plasma in ultra-relativistic heavy ion collisions.
