One of the best TV-series I saw the last couple of years is definitively Treme, set in New Orleans post-Katrina. Treme tells stories about people, inhumanity, dignity, resistance, death, individuality, fun, the Creole melting-pot and off course about jazz in almost all of its guises. And it has guest appearances by Elvis Costello, Dr. John, Allen Toussaint and many others.
You could watch below trailer, but you really should watch the entire series instead!
