  The paramagnetic metallic phase of the Anderson-Hubbard model (AHM) is
investigated using a non-perturbative local moment approach within the
framework of dynamical mean field theory with a typical medium. Our focus is on
the breakdown of the metallic phase near the metal-insulators transition as
seen in the single-particle spectra, scattering rates and the associated
distribution of Kondo scales. We demonstrate the emergence of a universal,
underlying low energy scale, $T_K^{peak}$. This lies close to the peak of the
distribution of Kondo scales obtained within the metallic phase of the
paramagnetic AHM. Spectral dynamics for energies, $\omega\lesssim T_K^{peak}$
display Fermi liquid universality crossing over to an incoherent universal
dynamics for $\omega\gg T_K^{peak}$ in the scaling regime. Such universal
dynamics indicate that within a local theory the low to moderately low energy
physics is governed by an effective, {\it disorder renormalised} Kondo
screening.
