This is a terrific review of the phenomenon surrounding the metal-insulator transition. I highly recommend it.
And if you think this is a boring topic (who cares about a metal-insulator transition?), read this review. In one swoop, this topic covers everything from high-Tc superconductivity to quantum phase transition. It also has a concise coverage of band structure description, why it works, where it doesn't, and why it doesn't. In the process, you get to learn about charge transport, charge localization, and a bunch of other fascinating stuff in the world of strongly-correlated systems.
