Simon Reynolds (for one) isn't having any of it

For the final night of Britain's Reading Festival on Aug. 28, the promoters have something unusual lined up to entertain the 80,000-plus rock fans who congregate there annually. On the alternative stage there will be a screening of Nirvana's legendary performance at Reading in 1992, when Cobain and his bandmates triumphantly headlined a bill of grunge and alternative rock groups they'd personally selected. In an interview earlier this summer, festival booker Tania Harrison declared, "It was such a legendary performance that so many people haven't seen ... one of those seminal moments that changed everything, which is what Reading's all about."

can't see anything wrong with this per se, but as Reynolds points out it's perhaps a smptom of 'retromania' and suchlike in general.
