Nirvana arrived at the Academy in December 1991 just at the point that 'Nevermind' was starting to sell by the bucketload and 'Smells Like Teen Spirit' was omnipresent.
The gig was originally scheduled for November. I'm not quite sure why the date change occurred.
This is a live bootleg reputedly recorded at the Academy gig. Trusted sources claim it to be genuine. It was posted to YouTube by Downer87.

The show opened with Kurt on drums, Krist on guitar, and Dave on vocals for an unknown song that was very similar to the instrumental demo reportedly recorded with the Drain You demo in spring 1991.
After one verse and one chorus of 'Polly' Kurt went into '(New Wave) Polly' which the band played in its entirety.
During the encore, Kurt switched to bass and Krist switched to guitar for the jam and unknown song. The last unknown song was also performed at the 11/25/91 radio session.
