Progress in computing excited state energies and meson-meson scattering phase shifts in lattice QCD are described. Such calculations are now possible using a stochastic method of treating the low-lying modes of quark propagation that exploits Laplacian Heaviside quark-field smearing. Level identification with a variety of probe interpolating operators is discussed.
