A recording of a one-of-a-kind Nirvana performance that took place 26 years ago briefly surfaced online for the first time. The gig at the Southern Bar in Edinburgh, Scotland was acoustic and featured Kurt Cobain on guitar and vocals while Dave Grohl played bass instead of drums. Nirvana bassist Krist Novoselic was there but did not participate. The duo played a handful of songs for the approximately 20 fans in attendance, including “Polly” and “Dumb.” The band were billed as “special guests” at the December 1st, 1991 show, which they played under the name “Teen Spirit.” While no recording of the acoustic show, which was a fundraiser for Edinburgh’s children’s hospital, had surfaced over the next two decades, 10 minutes from the performance was finally uploaded onto YouTube exactly 26 years after it happened on Friday, December 1st. Shortly after the audio was posted online, however, it was taken down to a “copyright claim” by the Recording Industry Association of America. The gig occurred a little over two months after the release of the band’s milestone album Nevermind, just as that LP and the single “Smells Like Teen Spirit” were beginning to explode across America.
