Background: Testament is an American thrash metal band from Berkeley, California. Formed in 1983 under the name Legacy, the band's current lineup comprises guitarists Eric Peterson and Alex Skolnick, lead vocalist Chuck Billy, drummer Gene Hoglan, and bassist Steve Di Giorgio. Since its inception, Testament has had numerous lineup changes, leaving Peterson as the only constant member. Billy replaced original singer Steve "Zetro" Souza (who left the band to join Exodus as the replacement of Paul Baloff) in 1986, prior to the recording of their first studio album, The Legacy, and has been a member of the band since.
Context: Testament's second album, The New Order, was released in May 1988, and found the band continuing in a similar vein. The album was a minor success, peaking at number 136 on the Billboard 200, and managed to sell over 250,000 copies. In support of The New Order, Testament opened for Megadeth on their So Far, So Good... So What! tour in Europe, and toured the United States with the likes of Death Angel, Vio-Lence and Raven.  After touring in support of The New Order, the band headed back into the studio to record their third studio album Practice What You Preach. Released in August 1989, the album minimized the occult and gothic themes found in the lyrical content of their first two albums, instead focusing on real-life issues such as politics and corruption. Practice What You Preach performed better on the charts than The New Order, reaching at number 77 on the Billboard 200, and included the hit single, the title track, which saw extensive airplay on Headbangers Ball. Testament toured for nearly a year behind Practice What You Preach with several bands, including Annihilator, Wrathchild America, Mortal Sin, Nuclear Assault and Savatage. By 1990, the album had sold over 450,000 copies.  In October 1990, Testament released their fourth studio album Souls of Black. Although reviews were mixed, the album managed to sell respectably, in no doubt largely off the strength of the single title track, and saw the band perform on arena tours, including the European Clash of the Titans tour with Megadeth, Slayer and Suicidal Tendencies. They also opened for Judas Priest on their Painkiller tour from October to December 1990, and Slayer on their Seasons in the Abyss tour from January to March 1991.  Attempting to reconnect with an audience distracted by the growing grunge movement, Testament released The Ritual in 1992. The Ritual saw a stylistic move away from thrash to a slower, slightly more traditional heavy metal sound. The Ritual peaked at 55 on the Billboard Hot 100, the band's highest chart position at the time, and the power ballad "Return to Serenity" managed to receive radio airplay, peaking at number 22. In support of the album, Testament toured Europe and North America, headlining their own tours, as well as opening for Iron Maiden on their Fear of the Dark tour, and Black Sabbath on their Dehumanizer tour. However, the success of The Ritual did not put an end to the tensions within the band.
