Now 56, Iggy Pop has reunited with the two other surviving members of the Stooges, brothers Ron (guitar) and Scott (drums) Asheton, on four of these hardcore tracks. Sum 41 and Green Day, two contemporary punk acts, collaborate on other numbers, as does Iggy's current tour band the Trolls. The results, alas, are not the equal of the Stooges' classic Raw Power or the best of Iggy's solo work, which lighten the hardrock attack with melody. Here the instrumentation on tracks like "Little Electric Chair" is dense as the heaviest metal. And ear-numbing, endlessly repetitive lyrics play like a jackhammer to the Skull.
