After going viral last year with her “Anaconda”-backed Unilever diss track, Sofia Ashraf is back. The Indian rapper – who’s been marketed as the country’s “first female raptivist” – has now published a new, equally political follow-up video: and this time, it’s Dow Chemical Company and the US government in the firing line.

The three-minute track, titled “A Toxic Rap Battle”, calls on Dow to take legal responsibility for the 1984 Bhopal Gas Tragedy, which saw 30,000 Indians die from a lethal gas leak. Despite the magnitude of the incident (which is widely considered the world’s worst industrial disaster), the Chemical Company has managed to evade justice for 32 years. The US Department of Justice has also refused to serve a court notice in that time.

In the video, Ashraf simulates a rap battle between Dow and the people of Bhopal, with the rapper taking on both roles. “This ain’t roadkill / death’s still taking it’s toll,” she accuses. “The field’s a mess and meals are less / and nevertheless you don’t seem to care.”

Ashraf also mentions the aftermath of the disaster, which saw an estimated 150,000 people suffer from exposure-related health effects; including cancer, neurological damage and mental illness. “The worst effects are the birth defects,” she raps, “that still affects even the third generation.”
