What Unreleased Songs Did Kurt Nirvana Record Before Fame?

I've dug through a stupid amount of bootlegs, box sets, and old forum threads over the years, and one thing that always fascinates me is how many raw, half-baked, and downright brilliant things Kurt recorded before Nirvana hit it big. The most famous of the pre-fame tapes is the 'Fecal Matter' cassette—Kurt's short-lived project with Dale Crover—which contains some of the earliest Kurt originals and sketches that later mutated into Nirvana staples. One track from that tape that most fans point to is 'Spank Thru', an unpolished little anthem that showcases how Kurt could turn the casual and comedic into something oddly touching. Beyond that, a lot of what he recorded in basements, on boomboxes, and in tiny studios were copies, covers, alternate takes, and straight-up experiments that circulated only on cassette until the posthumous box sets started cleaning things up.

If you want names and categories rather than just vibes, the early unreleased stuff falls into a few groups: the 'Fecal Matter' originals (tape-only gems), solo acoustic sketches Kurt recorded at home or for friends, early band demos with various lineups (Kurt + Dale, Kurt + Krist + Aaron Burckhard, and later with Chad Channing), and covers/medleys he loved to throw into practice. Many of these early versions are roughly the seeds of songs that later appeared in different forms on 'Bleach' or as B-sides. The 2004 box set 'With the Lights Out' collected a ton of those pre-fame recordings and demos—so while many were once truly unreleased or bootleg-only, some have since been officially released there. Other rarities and rehearsal tapes still survive mainly in fan circles and on YouTube, and they include off-the-cuff acoustic takes and studio run-throughs that never made a label release back then.

What’s endlessly cool to me is hearing the evolution: a half-finished riff on a cassette becomes a cleaner studio take years later, or a throwaway joke lyric from a basement session turns into the raw emotional punch of a single. Bands were less polished then, and Kurt recorded constantly—so a lot of material that technically existed before fame simply got reworked, re-recorded, or abandoned. Some songs existed only as fragments, lines, or chord progressions on tape, and you can hear how ideas were recycled between projects and eras. Collectors often point to early studio demos from 1987–1989 and the reciprocal studio sessions as fertile ground for these unreleased/bootleg tracks.

In short: if you’re looking for specific titles, 'Spank Thru' is the standout named track from the true pre-Nirvana 'Fecal Matter' era, and the rest are a mix of demo versions, covers, and sketches—many of which later surfaced on 'With the Lights Out' and other rarities compilations, while some remain circulation-only on bootlegs. Hunting these down is a rabbit hole in the best way: you’ll hear raw experiments, false starts, and flashes of genius that never reached the polished studio—exactly why I still keep replaying those old tapes whenever I’m in the mood for something a little rough around the edges.
