Roadie John Marshall, who also played guitar in "Metal Church", filled in for James Hetfield on rhythm guitar between July 27 and September 25 following a mid-tour skateboarding accident resulting in a broken arm.  Hetfield, Cliff Burton and Kirk Hammett originally decided to dismiss Lars Ulrich upon completion of the tour, but plans were set aside upon the death of Burton on September 27, 1986 in a tour bus accident near Ljungby, Sweden while en route from Stockholm to Copenhagen, Denmark.  Performances that were scheduled for October were postponed and the band hired a new bassist, Jason Newsted to complete the rest of the tour.

Metallica (album): Metallica (commonly known as The Black Album) is the fifth studio album by American heavy metal band Metallica.  Released on August 12, 1991 by Elektra Records, it received widespread critical acclaim and became the band's best-selling album.  "Metallica" produced five singles that are considered to be among the band's best-known songs, which include "Enter Sandman", "The Unforgiven", "Nothing Else Matters", "Wherever I May Roam", and "Sad but True". " Don't Tread on Me" was also issued to rock radio shortly after the album's release, but the song did not receive a commercial single release.  The album marked a change in the band's sound from the thrash metal style of the previous four albums to a slower one.  Metallica promoted the album with a series of tours.  In 2003, the album was ranked number 252 on "Rolling Stone"' s 500 greatest albums of all time.

St. Anger: St. Anger is the eighth studio album by American heavy metal band Metallica, released on June 5, 2003, by Elektra Records.  It was the band's last album released through Elektra, and the second-longest timespan between studio albums from Metallica, with nearly six years between the release of "Reload" and this album.  It is also the final collaboration between Metallica and producer Bob Rock, whose relationship began with the band's fifth studio album, 1991's "Metallica".  "St. Anger" was originally intended for release on June 10, 2003, but was released five days earlier due to concerns over unlicensed distribution through peer-to-peer file sharing networks.  The "St. Anger" sessions also mark the only time Rock played when the music was being recorded, filling in for the departed bassist Jason Newsted.

Ride the Lightning: Ride the Lightning is the second studio album by American heavy metal band Metallica, released on July 27, 1984, by the independent record label Megaforce Records.  The album was recorded in three weeks with producer Flemming Rasmussen at the Sweet Silence Studios in Copenhagen, Denmark.  The artwork, based on a concept by the band, depicts an electric chair being struck by lightning flowing from the band logo.  The title was taken from a passage in Stephen King's novel "The Stand".  Although rooted in the thrash metal genre, the album showcased the band's musical growth and lyrical sophistication.  This was partly because bassist Cliff Burton introduced the basics of music theory to the rest of the band and had more input in the songwriting.  Instead of relying strictly on fast tempos as on its debut "Kill 'Em All", Metallica broadened its approach by employing acoustic guitars, extended instrumentals, and more complex harmonies.  The overall recording costs were paid by Metallica's European label Music for Nations because Megaforce was unable to cover it.  It was the last album to feature songwriting contributions from former lead guitarist Dave Mustaine.
