by Greg PratoWhen AC/DC exploded on the charts in the early '80s (thanks to the blockbuster classics Back in Black and Dirty Deeds Done Dirt Cheap), there suddenly seemed to be legions of groups that sonically emulated the group -- especially their "Bon Scott era." Included in this "pack" were Rose Tattoo, Angels (also known as Angel City), and Heaven. But the one that enjoyed the most success stateside was Switzerland's Krokus, thanks in part to a plumb opening spot on Def Leppard's sold-out Pyromania tour, and moderate hit albums (1983's Headhunter and 1984's The Blitz). But the group (which was fronted by Marc Storace, undoubtedly one of the more interesting-looking singers in metal history) was unable to sustain its success and, throughout the '90s and early 21st century, would reunite for new albums and tours, with various members coming and going. 2003's Rock the Block was the first Krokus release to see Storace behind the mic in some time, and unlike when they were obviously trying to score a glossy radio hit in the mid-'80s, Rock the Block sees a band that has gotten back to its AC/DC roots, as evidenced by such tracks as "Mad World" and "I Want It All."
