Killer!
You don't need more to say about one of the best Swedish Heavy Metal Releases ever made.
Maybe, only their 7" with "Gotham City" and "Killer Angels" is a bit better, but this EP's just full of Killer, no filler. The Cover is a killer, too!
Speed Metal Songs like "Monsters of Rock" and a Hymn like "Born to Rock Hard" should be known to every Hard-Rocker on this planet.
If you don't know these songs, if you don't know Gotham City, better go home, grab your pillow and cry like the sissy that you are!
All others Raise them Fists and sing along to "Monsters of Rock":
"Heavy Metal is Loud, Heavy Metal is Proud!"
