I discuss the unusual electrodynamics observed in the metallic state of various low dimensional metals which at low temperatures develop charge density wave (CDW) and spin density wave (SDW) ground states. In all cases, we observe a low energy mode with a small spectral weight and a finite energy excitation. These results suggest a highly unusual metallic state. The findings will be contrasted with the theoretical models of low dimensional metals.
