With the official Amy Winehouse documentary, Amy, hitting US theaters this Friday, July 10th. Today, we get another glimpse into Amy’s life with another leak from the forthcoming clip. Today’s clip features her recording “Back to Black” with Mark Ronson.

This is probably the most epic piece of footage that we’ve seen to this date. Wow.

“It was just one of those serendipitous things—I just caught her at that magic moment,” says Ronson. “She was just ready to get it going, that’s why I couldn’t understand what everyone else was saying about this procrastinating, troubled artist.”
