It was the first TNT album recorded with their new vocalist Tony Harnell, who had replaced their original singer Dag Ingebrigtsen.

Most of the songs on the album had been written and recorded as demos while Ingebrigtsen was still in the band, but most of the lyrics were rewritten by Harnell.

Some of the song titles were also changed; "Toys for Boys" and "Black Sheep of Valhalla" became "Break the Ice" and "Knights of the Thunder", respectively.

[3] Two songs from TNT's self-titled first album, "USA" and "Eddie", were re-recorded and included on the album, though "Eddie" was an exclusive bonus track on the CD edition in Europe,[2] and replaced "Tor with the Hammer" on U.S. editions.

[4] The album's original cover art featured an illustration of half-naked women and caused controversy in Norway.
