Check out the video for "Wolf's Blood" from Swedish thrashers Wolf: http://www.wolf.nu/mp3/wolf%20-%20wolfs%20blood%20320x240.wmv
The look of the clip is described as "Thin Lizzy at 'Top of the Pops' '77 meets Judas Priest at Budokan in '81." As for the sound, I'd say they perfectly combine the best qualities of Mercyful Fate and Iron Maiden.
