When i was younger and just began diving into hard rock and heavy metal i remember how impressed i was with Judas Priest covers.
This eagle falling from the sky and a metal cat – these pictures I have met in many other magazines later on (holding now cover of the Hungarian LPM magazine from January 1990), this style and energy is still inspiring people. I have seen a magazine in Russia with cover image made with a Judas Priest “Turbo” cover just last year.
These illustrations were made by Doug Johnson, one of the most interesting illustrators of the 80’s IMHO.
Here is the cover for Bo Diddley’s “Where It All Began”
Fantastic style, isn’t it? No Photoshop or Illustrator, ma!
Here you can find the page with more info about him and several cover art works presented.
