It's possibly the greatest ever example of artistic censorship in Australian history. Police have requested hip hop to be taken off online streaming platforms, stopped bands from performing in Australia, and amended visa regulations so local hip hop artists can't perform overseas. Their claim is that hip hop is inciting violent and criminal behaviour. But it's an old debate that first emerged in the birthplace of hip hop more than two decades ago. Osman Faruqi shines a light on parallels to the hip hop wars of 1990s America, the role of police bias and profiling, and concerns for free speech more broadly.
