In 2011 drummer Arin Ilejay joined the band on tours and recording. The band's sixth studio album "Hail to the King", which was released in 2013, marked the only Avenged Sevenfold album featuring Arin Ilejay. "Hail to the King" charted as number 1 on the "Billboard" 200, the UK Albums chart, as well as the Finnish, Brazilian, Canadian, and Irish charts. In late 2014, Ilejay left the band, and was replaced by former Bad Religion drummer Brooks Wackerman, but the lineup change wasn't announced to the public until 2015. The band then surprise-released their seventh studio album titled "The Stage" on October 28, 2016, which debuted as number 4 on the "Billboard" 200 chart in the US. "The Stage" is their first conceptual album and it marked another stylistic change for the band, moving towards the progressive metal sound.
