Metallica have posted behind-the-scenes footage from their Rock In Rio performance. The video features the members of the band back-stage in the tuning room, where they rehearse 'Whiplash'.
Later on in the video, the band perform Orion (on stage this time), and you can watch all of this in the video above.
Keep an eye out for James Hetfield's signature Snakebyte guitar, which you can find out more information on here.
