Avenged Sevenfold was invited to join Ozzfest tour on the main stage, alongside other well known rock/heavy metal acts such as DragonForce, Lacuna Coil, Hatebreed, Disturbed and System of a Down for the first time in 2006. That same year they also completed a worldwide tour, including the US, The United Kingdom (as well as mainland Europe), Japan, Australia and New Zealand. After a sixteen-month promotion of "City of Evil", the band announced that they were cancelling their Fall 2006 tour to record new music. In the interim, the band released their first DVD titled "All Excess" on July 17, 2007. "All Excess", which debuted as the No.1 DVD in the US, included live performances and backstage footage that spanned the band's eight-year career. Two tribute albums, ' and ' were also released in October 2007.
