I have covered the lyrical content on this album in the past so here, I will just discuss the music. King Diamond is doing what the band does best here: powerful traditional metal in the vein of Judas Priest and Iron Maiden. The riffs are powerful and fast, the drumming precise, and the bass throbbing.
Of course, the vocalist is the star here. King puts forward one of his strongest vocal performances on this album. His falsetto is in top form and his other vocals are also powerful.
This is easily one of King Diamond's best albums. I would write more, but this album has been covered previously.
