You really have to ask, what should have this publication for a purpose. Who is Nirvana fan, the box has already. And for beginners Nirvana is such a compilation of live and demo versions unsuitable. Here are, in fact, it almost only pieces that you already got to hear in the box. Even the booklet's content and presentation of the box to that borrowed. Here also nothing new. And of the three unreleased tracks is "Spank Thru" worth mentioning - a song from the early phase of the band and then in the Seattle scene a minor hit - that on the "Incesticide" quite a few fans - had missed CD. The other two pieces are alternative versions of known songs, so unnecessary. Should you buy the CD so because of a single new song? This CD is only worthwhile for people to whom the box was too expensive.
