Pantera famously began their career as half-successful glam rockers, before finding their voice by downtuning their guitars and pursuing a far heavier path. Their transition mirrored the metamorphosis of hard rock in the early 90s into something angry and chaotic, while underlining that it’s ultimately a performance of chaos, a new way to excite the fans. Some of the most powerful moments in this set happen when the players stop just short of exploding, like the expertly balanced tension and release of “Breadcrumb Trail,” or the deadly, caustic crawl of “Then Comes Dudley.”
