Holographic techniques have been widely and successfully used to describe strongly coupled fluids. In this talk I will review how bottom-up holographic models can be extended to include also solid and especially viscoelastic phases of matter. I will show how to formalize the (visco)-elastic response and I will discuss in details the vibrational phononic degrees of freedom from an holographic perspective. Finally I will discuss two specific open problems using both holographic methods and effective field theory condensed matter techniques: 1) the density of states and thermal transport anomalies in glasses, amorphous solids and more recently even ordered crystals 2) the observation of low frequency propagating shear waves in liquids and its theoretical explanation No detailed knowledge of AdS-CMT methods is required and lot of low energy condensed matter will be present
