I will discuss recent progress in extracting excited meson spectra and radiative transition rates using lattice QCD . I will explain some of the techniques used, but also emphasise results, their interpretation and relevant experiments. Results on the light meson spectrum will be presented where a combination of new techniques have enabled us to extract a very extensive spectrum, including many states with exotic quantum numbers and, for the first time, spin-four states. I will also mention some results in the charmonium sector, including the first lattice QCD calculation of radiative transition rates involving excited charmonia, highlighting results for exotic states and interpreting the results phenomenologically. I conclude with some comments on future prospects.
