One week ago today, Dave Grohl, Trent Reznor, Josh Homme, and Fleetwood Mac’s Lindsey Buckingham capped off the 2014 Grammy Awards with a blitzing performance…. that was cut short in favor of a Delta Airlines commercial. But now, fans can watch the performance as it was originally intended thanks to an uncut rehearsal video (via Antiquiet). Watch the once-in-a-lifetime rock ‘n’ roll super group tear through Nine Inch Nails’ “Copy of A” and Queens of the Stone Age’s “My God Is the Sun” below.
