Black Sheep Hit: "Aneurysm", the song was only a B-Side and later was ranked in third place for best Nirvana song, right under "Smells Like Teen Spirit" and "Heart Shaped Box".
Made all the more impressive since it was the final track on the Smells Like Teen Spirit single and the final track on their 15 song compilation album released in 1992.
Colbert Bump: Kurt loved to talk about his favorite bands in interviews. Some of these bands received a lot of attention after Cobain plugged them. The Vaselines were virtually unknown in the United States until Cobain declared them to be his favorite band.
Creator Backlash: Kurt eventually got so fed up with the excessive focus on "Smells Like Teen Spirit" that he would purposely trick and antagonize crowds at some of the shows, if they insisted that the band play the song. Most often, he would play the intro to Smells Like Teen Spirit, and go right into Rape Me (with a similar opening riff) instead.
In the UK on Top of the Pops (which is known for its making bands mime performances to a pre-recorded backing track - basically one step above lip-synching), Kurt sang in a deep voice to annoy the people insisting he play Smells Like Teen Spirit, and to imitate Morrissey.
Magnum Opus Dissonance: Kurt thought of "Smells Like Teen Spirit" as a highly polished Pixies rip-off and was often reluctant to play it. He actually considered "Drain You" to be the best song on Nevermind, as well as one of the best songs he ever wrote.
This might be sacrilege, but one of the cartoon bands on Jem and the Holograms was called Nirvana.
Confusingly, Nirvana sort of ended up calling two unrelated songs "Verse Chorus Verse" - one was an outtake from 1991, the other was their contribution to the 1993 compilation No Alternative. Fanon started dictating that the 1991 song was the real "Verse Chorus Verse" and the 1993 song was "Sappy" (a known Working Title), and this was essentially made canon by the track-listing to the box set With The Lights Out, which featured both songs.
No Budget: Bleach was recorded on a budget of just over $600. Guitarist Jason Everman supplied the money. He is credited as a guitarist on the album, though he didn't actually play on it.
Promoted Fanboy: Cobain always made sure to plug his favorite bands in interviews and several of them (Meat Puppets, The Melvins, The Vaselines and Shonen Knife, just to name a few) got major label record deals just because Cobain said he liked them. Nirvana also got a record contract thanks to the support of Sonic Youth, a band they were all big fans of and quickly befriended afterwards.
Odd Friendship: At the height of the Hype Backlash surrounding "Achy Breaky Heart". Cobain met and struck a friendship with country star Billy Ray Cyrus, quipping something like, "Congratulations on getting the whole world to hate you". This is ironic considering the backlash Cyrus' daughter (a Nirvana fan) recieved in 2012 from some rock purists for covering "Smells Like Teen Spirit" in concert. Krist Novoselic did defend and support Miley for her cover, though.
Throw It In: While working on Bleach, the band had been experimenting with Drop D tuning. Before recording "Blew", Krist Novoselic had forgotten that he'd left his bass in drop D, so he re-tuned it as though it was in standard tuning to begin with, ending up recording his part in drop C#. This was the take that was used for the album because it just sounded cooler.
Nevermind has two mistakes that were left in: on "Polly", Kurt accidentally starts the "Polly says" verse too early, pauses, and then re-starts on the right spot. This became a sort of Ascended Glitch, even appearing on the faster "(New Wave) Polly" version from Incesticide. During double-tracking for "Come As You Are", he similarly sang "And I don't have a gun" before the last "memoria, memoria" section was over, but saved the mistake.
