Dr. Dre recently previewed a song in the studio via a video clip shot by Lemar Guillary, a professional trombonist.

Guillary lensed the video before laying down the horns on the track. In the clip, the West Coast veteran presents the cut, which features plucked strings and a heavy bass.

Watch the video below (via HHNM).

UPDATE: HipHopDX has learned that the studio footage was previously released.
