"Award-winning dramatist Stephen Poliakoff (The Lost Prince; Close My Eyes) blows open the volatile world of 1930s London, in a story about a black jazz band's rise to success, before violence and prejudice brings it crashing back to earth.
Set in an extraordinary period of immense change, the Louis Lester Band arrives at the forefront of an emerging musical movement: jazz. As the band grows in popularity and starts to mix with the upper classes, the intoxicating combination of music and parties pull the characters into a gilded but perilous world. Soon the band begins to feel immune from the prejudice hovering beneath the surface of society, but the sudden death of one of the band members creates a catastrophic turn in their fortunes. They immediately find themselves confronted by betrayal, and their privileged position is torn away from them as they begin to discover who their friends are. A stellar cast including Chiwetel Ejiofor(American Gangster; Salt), John Goodman (The Big Lebowski; The Artist), Matthew Goode (A Single Man; Brideshead Revisited) and Jacqueline Bisset (Bullitt) star in this explosive new drama, where for a moment music transcends the divisions of class and race, until fear and hate once again tear them apart."
