All and Bonded by Blood. The tour cycle for Ironbound ended in South America in the fall of 2011. In July 2011, Overkill began demoing six songs and were planning to begin recording their 16th album in October for an early 2012 release. The resulting album, The Electric Age, was released on March 27, 2012, and it was the band's first album to enter the top 100 on the Billboard 200, peaking at number 77; this was also Overkill's highest-chart position at the time. In 2013, the band embarked on The Dark Roots of Thrash tour of North America, headlined by labelmates Testament along with Flotsam and Jetsam, and 4Arm. However, they canceled their February 15 show in Huntington at The Paramount Theatre due to singer Bobby "Blitz" being diagnosed with "walking pneumonia". On February 18, it was announced that Overkill was officially dropped out of the Dark Roots of Thrash tour as Blitz's condition had gotten slightly worse after the show in Worcester, Massachusetts. On August 31, 2013, Overkill entered Gear Recording on to begin recording their seventeenth studio album. The album was going to be released on March 7, 2014. On January 14, however, it was announced that the album was postponed to July. On March 15, it was revealed that the new album was going to be titled White Devil Armory. After some delays, White Devil Armory was finally released on July 22, 2014. The album was their most successful; it peaked at #31 on the Billboard 200, making it Overkill's highest chart position so far. On November 5, 2015, it was announced that Overkill would play a special show on April 16, 2016 in Oberhausen where they played the Feel the Fire and Horrorscope albums in their entirety. The show was professionally filmed and recorded for the DVD Live in Overhausen, which was released on May 18, 2018. Overkill released a box set, titled Historikill: 1995–2007, on October 16, 2015. To support the box set, Overkill embarked on a North American tour with Symphony X in September–October 2015, and a UK tour in April 2016. In a September 2015 interview, Bobby "Blitz" Ellsworth revealed that Overkill had begun writing their eighteenth studio album, and by March 2016, they had "fully demoed" eleven songs for it. Ellsworth said in a March 2016 interview that Overkill would begin recording the album in early May for an October release.
