The AdS/CFT correspondence provides a powerful framework for studying strongly coupled field theories using gravitational techniques. Motivated by possible applications to condensed matter systems many novel classes of black hole solutions have been discovered over the past few years. In this talk, we review progress in understanding of black hole solutions that are holographically dual to conformal field theories that have been deformed by operators that break translation invariance. Such UV deformations provides a mechanism by which momentum can dissipate and we show how the thermoelectric DC conductivity of the CFT can be obtained by solving Stokes equations for a charged fluid on the black hole horizon. We also discuss how the black holes provide a framework for finding holographic descriptions of metals (both "coherent" and "incoherent"), insulators as well as transition between them.
