Vibe was on hand at The Roots' 6th Annual Pre-Grammy Jam Session to get more video footage of this past weekend's festivities. In this clip, former band member Scott Storch joins The Roots crew on the keys to perform the beat for Dr. Dre's "Still D.R.E." (Storch co-produced the track), while Black Thought gets busy on the mic. Check out Vibe for Scott's post performance interview.
