ALLTEL PAVILION–To understand the beauty of DragonForce is to forgive the UK power boys for unwittingly cribbing the verse chords off Garth’s “Thunder Rolls” in their callisthenic metal workout “Through the Fire and Flames.” It’s also the ability to overlook the fact that the phrase “through the fire and flames” appears in two different songs on their latest Roadrunner release, Inhumane Rampage. But most importantly, it’s the ability to appreciate song-spanning wankery, meteor tempos and every power metal calling card under the blistering sun. A day at Ozzfest never sounded so epic. The all-day event runs $20-$107. –Robbie Mackey
