the big problem with Nirvana, is that they never released their best work and only a fraction of which was released on the box set. I'm talking about songs like Sappy, Verse Chorus Verse, Song in D (which most likely has already surfaced on an acoustic demo), Old Age, Do Re Mi (there's a version recorded with a full band), Weird Radio Jam (recorded in Holland), Dave's Meat Song, and probably a bunch more that we've never even heard of.
