We're less than 24 hours away from hearing a new album from Dr. Dre and thanks to a new bit of Straight Outta Compton movie promo we now have an unexpected early peak at one of the tracks. Beats By Dre released a short promotional clip on Twitter tonight featuring interview footage with YG, Boogie, DJ Quik​, and more and there's a conspicuously new track playing along in the background. Near the end of the almost two-minute long clip we get an even more unexpected preview: Dre is actually rapping on the song too.

Watch the Straight Outta Compton lead-up below and tune into Apple Music tomorrow night to catch an exclusive first listen of Dre's new record. 

Listen to the premiere of @drdre new album, Compton. Uncensored & exclusively on @AppleMusic, from 6pm - 9pm PDT Thursday August 6th.
