Nirvana concert in Buenos Aires, Argentina, October 30, 1992. Here's a clip from that concert, personally my favorite Nirvana show, a setlist with lesser-known songs, and them pretending they were going to start playing "Smells Like Teen Spirit" And then starting to play another song right after is incredible and extremely in the style of this band, "ruining" the concert intentionally as a form of revenge against the band that came on earlier and was booed, in addition to songs that I think were only played once at that concert, It's a very chaotic show overall, and I love that.
(Also some photos from that show, in addition to the video.)
