Nine Inch Nails, Queens of the Stone Age, Dave Grohl, and Fleetwod Mac‘s Lindsey Buckingham closed out the Grammys, but their performance was cut off by a commercial for Delta Air Lines. Trent Reznor was not happy about it at all, and there’s no blaming him really. Fortunately, the full rehearsal footage of the supergroup performing “Copy of A” and “My God Is the Sun” has surfaced online. Whilst the footage is a little quiet, it’s nice to see them perform without random footage of airplanes appearing out of nowhere.
