Metallica has dug into its vaults to release a recording of a vintage concert from London as well as behind-the-scenes video clips from the sessions for 2008's Death Magnetic album. The London concert was recorded on September 21st, 1986 and featured guitar tech John Marshall playing guitar for an injured James Hetfield. It was also one of bassist Cliff Burton's final gigs before his death six days later in a tour bus crash.
