$O$ is the debut album by South African rap-rave group Die Antwoord. The record was a broadly circulated web-only release, and made accessible to stream free of charge on the web site of the group before Interscope Records signing the group. “Fish Paste” and “Beat Boy” have also been released as promotional singles. “Enter the Ninja” debuted at #37 in the united kingdom Music Charts on September 19, 2010.

Following the group’s signing to Interscope in the US, it was declared that $O$ would be re-released in physical format here with an alternate track listing. Diplo created one of the brand new tracks on the re-release, “Evil Boy”, for which a promotional video was made accessible on 6 October 2010.
