input: 1987 saw the release of their second album, Bangin'. This album did not achieve the acclaim of Play Deep, but it did spawn a Top 40 single "Since You've Been Gone" (not to be confused with the 1970s Rainbow and Head East hit of the same name) and the minor radio/MTV hit "No Surrender", and the album was certified Gold in the US A US summer tour opening for Night Ranger followed. For the group's third album, 1989's Voices of Babylon, a new producer (David Kahne) and sound was evident. The title track was a Top 25 single and "My Paradise" was a mid-sized album-rock hit, but overall the group's popularity continued to decline. After the Babylon LP, Alan Jackman parted ways with the band and was replaced for a concert tour by Paul Read. Spinks and Lewis continued as a duo, switched labels and began recording Diamond Days for MCA. Playing drums on the disc was session drummer Simon Dawson. The LP, released in 1990, produced a Top 30 US hit, "For You". Quick to follow was "One Hot Country", included on the soundtrack for the 1991 action film If Looks Could Kill. The Outfield returned with 1992's Rockeye. Its leadoff single, "Closer to Me", was a near Top 40 hit, and a second release, "Winning It All", gained some notice due to extensive play during NBC's NBA Finals coverage, NBA Superstars series featuring Larry Bird, the 1992 Barcelona Summer Olympics and the film The Mighty Ducks. Simon Dawson, who played on Rockeye, would eventually become the band's official third member.

input: As early as 2009, Testament commenced writing new material for their tenth album. In an interview with Metalheadz, guitarist Eric Peterson stated that there were about four songs written and that "there's other guys in the band who like to play the more rock melodic style but the next one is gonna be a bit heavier." In a January 2011 interview during the 70000 Tons of Metal cruise, frontman Chuck Billy revealed that Testament had been working on six new songs, with four or five "maybe left to write," and would begin recording their new album by early March. On 18 May 2011, guitarist Alex Skolnick posted an update on his Twitter, saying, "Another tune done! My riffs from last week [plus] some of [fellow Testament guitarist Eric Peterson's plus] new ones we wrote today. Planning one more, then we've got more than we need." Testament began recording their tenth studio album on June 20, 2011. Drummer Paul Bostaph was unable to take part in the recording due to a "serious injury", although he was expected to rejoin when the band tours to support the album. Gene Hoglan, who played drums on the band's 1997 album Demonic, filled in for Bostaph. It was also reported that Lamb of God drummer Chris Adler would make a special guest appearance on a couple of bonus tracks. Testament appeared at the California dates of the summer 2011 Rockstar Energy Drink Mayhem Festival, replacing In Flames. On 14 July 2011, it was announced that the tenth Testament studio album would be called Dark Roots of Earth, which, after many delays, was released on July 27, 2012. Dark Roots of Earth debuted at No. 12 on Billboard 200, the band's highest chart position to date. Prior to the album's release, the band toured in the fall of 2011 with Anthrax and Death Angel. Overkill was invited to the tour, but due to the pre-production of their sixteenth studio album The Electric Age, they did not participate. It was announced on 1 December 2011 that Paul Bostaph had left Testament. Gene Hoglan recorded the drum tracks for Dark Roots of Earth and continues to play live with the band. In interviews, Testament have expressed pleasure in Hoglan's playing, and hope that he would continue playing with the band for the foreseeable future.

input: On January 1, 1991, the band held their first concert in Nippon Budokan and their first tour from March through April, before releasing any music. On September 9, 1991, they released their first single, "Can't Stop -Loving-" from Victor Entertainment, which peaked at #2 on the charts. Subsequent singles, "Seigi no Mikata wa Ate ni Naranai", "Kokoro no Kagami", "Makeru na Baby" peaked in the top 10. The band asked the fans to write the lyrics for "Kokoro no Kagami", and the one submitted by a fourteen-year-old girl was chosen. The song was later used in a Panasonic television commercial. They were invited to perform the song at Kohaku Uta Gassen, an annual music show, on December 31, 1991. At the same time of their debut, the Japanese music industry experienced what is frequently referred to as an "Idol Ice Age", where many of the popular music shows that aired weekly since the 1980s ended, and singers and bands lost a place to perform, resulting in scarce opportunities for TV exposure. Therefore, the agency decided to market the band through variety programs, where members participated in sketch comedies and game shows along with other television personalities. This non-mainstream marketing approach turned out to be a success, as the members' humorous and playful spirits on these shows propelled them to gain new fans, despite not having many musical performances on television since their debut. In 1991, the band's first self-titled television show, SMAP no Gakuen Kids, got renewed and changed to, I Love SMAP, which aired until 1996. From October 7, 1991, Inagaki launched his radio program, Stop The SMAP, still airing as of 2016. From April 1992 to September 1995, the group appeared regularly on a weekly variety program, Yume ga Mori Mori. Due to the fact that this was the first time in Japanese history, that a band participated in a sketch comedy, this rare act attracted wide attention. On January 1, 1992, they released their first album, SMAP 001, which peaked at #14 and released another album, SMAP 002, in the same year and peaked at #6. Their singles, "Egao no Genki", "Yuki ga Futtekita", "Zutto Wasurenai", "Hajimete no Natsu", "Kimi wa Kimi dayo", "$10", and "Kimi iro Omoi", released from 1992 through 1994, all peaked at the top 10. They headlined three tours in 1992, from January to August. In 1993, they released their third and fourth album, SMAP 003 and SMAP 004, which peaked at #11 and #3 respectively. In 1992, Inagaki starred in a drama television series, Hatachi no Yakusoku, as the main role. In 1993, Kimura starred in a drama television series, Asunaro Hakusho, which became a massive hit, with an average household share rating of 27% and 31.9% for the season finale. Kimura's popularity soared and from then on, members of the band started their acting careers individually.
