AC/DC's 19th studio album (if you count their two Australia-only albums, TNT and the original High Voltage), 2001's Stiff Upper Lip proved to be a rather weak outing when it came to spawning successful singles -- basically, the title track worked, and that's it. Released in a hundred different single formats, on this EP the title track takes an instant back seat to the album's only known outtake/B-side, the very straightforward but still wonderfully raucous "Cyberspace." And the fact that the members of AC/DC probably know nothing about cyberspace quickly becomes irrelevant, since it's almost impossible to decipher what in blazes Brian Johnson is screeching about. No matter, as this sweet little collector's item is rounded out by three choice live versions of "Hard as a Rock,""Back in Black," and "Whole Lotta Rosie." ~ Ed Rivadavia, All Music Guide
