Despite the happy news of the birth of Frances Bean Cobain a mere 12 days before this August 30 festival, rumors swirled around Nirvana right up until the band hit the stage. Kurt Cobain took full advantage of these scurrilous stories, making his entrance in a hospital gown and wheelchair pushed by journalist Everett True. Cobain feebly reached for the microphone to croak out the opening lines of "The Rose," only to collapse onto the stage, milking the drama for a moment before leading Krist Novoselic and Dave Grohl through a ferocious "Breed." This impish sense of humor has been obscured over the years, lost under the weight of the band's tragic legacy, along with the fact that Nirvana could actually be fun as well as furious. Live at Reading brings all this roaring back. This is Nirvana's purest blast of rock & roll: there's a boundless, invigorating energy here and, just as importantly, there's a sense of joy to the performances, a joy that bubbles to the surface when Kurt laughs during the intro of "Sliver" but can be heard throughout the show, as the band rushes in tandem, pushing the tempos on "Aneurysm" and "Territorial Pissings," ebbing and flowing as one. Hints of this could be heard on the live comp From the Muddy Banks of the Wishkah, but this is a complete document of Nirvana in full flight and one of the greatest live rock & roll albums ever.
