An adrenalin-charged trip through some of the cultural flashpoints of the past few decades, Pop Grenade celebrates the power of music as a force for change. Based on first-hand, personal reportage from raves, riots and rebellions, it explores how music has been used as a weapon in struggles for liberation and attempts to create temporary paradises. From Berlin's anarchic techno scene after the fall of the Wall to outlaw sound systems in wartime Bosnia, from Moscow during the crackdown on Pussy Riot to New York in the militant early years of hip-hop, it tells the extraordinary stories of some of the world's most audacious musical freedom fighters, disco visionaries and rock'n'roll rebels with a cause.
