Two long years after his last musical release, but less than one short week following his announcement of his new documentary series The Defiant Ones, Dr. Dre has dropped a new track titled "Gunfire." The song will be featured in the documentary series.

Each of the four episodes will track the story of Dre and music industry mogul Jimmy Iovine. After premiering on Sunday, the series has drawn surprise and acclaim for tackling one of Dre's more notable controversies in 1991, when he assaulted journalist Dee Barnes.

"Gunfire" will appear in the fourth episode of The Defiant Ones. Hear the audio below.
