Sub Pop put this awesome box set out in 1996, in conjunction with the release of the Hype! documentary. That doc was everything to me at the time. It was so great seeing some of the smaller bands I loved getting some screen time. The box set was actually a really solid representation of Seattle, if such a thing could be done with 11 tracks on four 7"s. The Nirvana track they included was "Negative Creep", and there was nothing special about this version - it was the same one that was on Bleach. There was only one pressing of the box set - it was an edition of 2,000 copies. Each 7" was on a different color of vinyl: Disc 1 (U-Men/Soundgarden) was on purple marble vinyl, Disc 2 (Wipers/Mudhoney/Nirvana) was on green marble, Disc 3 (Gas Huffer/Mono Men/Girl Trouble) was on grey marble, and Disc 4 (Fastbacks/Flop/Young Fresh Fellows) was on light blue marble.
The Box set never really became that valuable. What did happen was people started breaking the set into individual 7"s and selling them that way, and for some reason, that proved profitable. I guess people just wanted the individual Nirvana or Soundgarden 7"s or something.
