Surviving members of The Doors were in the studio with Skrillex. Nas and DJ Premier wrote with the Berklee Symphony Orchestra. The Crystal Method collaborated with Martha Reeves (The Vandellas) and The Funk Brothers. Pretty Lights recorded with LeAnn Rimes. Mark Ronson sat in on a session with Mos Def, Erykah Badu, The Dap Kings, Trombone Shorty, and Zigaboo Modeliste.

It all happened.

And it’s being shown during Grammy week in the documentary Re:Generation Music Project. Directed by Amir Bar-Lev (My Kid Could Paint That) it follows five influential producers (Skrillex, DJ Premier, Mark Ronson, The Crystal Method, and Pretty Lights) as they each collaborate with other influential artists across genres.

The documentary is being shown in US theaters for two nights only (Feb. 16th and 23rd). Fortunately, two of those locations are in Colorado. One of them is the Northfield 18, the other is the AMC Highlands Ranch 24. Tickets are on sale.
