Within the album, nods to the sound of past albums and songs are found, as well as lyrics that apparently reference earlier songs. The song "Demonizer" references both "The Hellion" from Screaming for Vengeance as well as "Painkiller" from Painkiller. "Hellrider" mentions the title track of Ram It Down, and "Tyrant" from Sad Wings of Destiny. "Eulogy" references "Stained Class" and "The Sentinel" from the albums Stained Class and Defenders of the Faith, respectively. Finally, "Worth Fighting For" acts as a sequel/prequel to "Desert Plains" from Point of Entry.
The song "Deal With the Devil" can be viewed as an autobiography of Judas Priest, telling their origins from the Black Country of England's West Midlands, mentioning their transitory days gigging around England and practicing at the Church of Holy Joseph in Walsall, which is where Judas Priest was effectively born. "Deal With the Devil" also mentions the song "Blood Red Skies" from Ram it Down, "Take on the World" from Hell Bent For Leather as well as "Beyond the Realms of Death" from Stained Class.
The album was released on the DualDisc format, which had traditional CD content on one side, and DVD content on the other side. The DVD side of this album contained a documentary entitled "Reunited", as well as the entire album in an enhanced audio format. In Japan it was released as a 2-disc set containing Compact Disc audio and DVD video.
