Finally done watching/listening to the whole thing. Here are my highlights, excluding the ones I already mentioned...
The Jury tapes (Ain't It A Shame in particular)
Opinion (great song, poor performance)
Lithium (nice acoustic version, but the chorus is a bit off-key)
Verse Chorus Verse (amazing outtake, too bad it has scratch vocals)
Old Age (ditto)
Rio demos (generally cool stuff, but Gallons shouldn't have been on there)
1993 solo acoustic In Utero songs
Sappy (previously available, but still a great song that needed a fair, upfront release)
Do Re Mi (even less than a month before his death, Cobain was writing classics...blew my expectations away for the box single-handedly)
You Know You're Right solo acoustic 1994 (very interesting different version, Cobain sounds very frail)
All Apologies undated (great ending)
As for the DVD, I like it for the most part. The 1989 rehearsal was cool (and brings to light just how great of a drummer Chad Channing really is), it's great to see Jason Everman play second guitar on Big Cheese, the 1989 random tour footage is great, and the early live Sappy is very interesting. While I would've rather had another live video, the Sub Pop In Bloom music video is pretty cool to have. School with Danny Peters drumming is amazing, as is the first performance of Smells Like Teen Spirit (at least from a historical standpoint), and Jesus Doesn't Want Me from Halloween 1991 looks really cool and professional. Talk to Me is a great song (sadly never studio-ized), and the Seasons in the Sun video is absolutely beautiful. The rest of the footage is pretty blah, though...but the bonus footage on the menus is awesome. Oh, by the way, at the end of the credits, hit enter and you'll get bonus footage of Dave Grohl screwing around outside with a huge cymbal...pretty funny.
Anyway, Jack Endino predicts the next Nirvana releases will be a bunch of soundboard bootlegs of shows a la Pearl Jam's insane collection of shows officially released...I sure hope so. More DVDs would be nice too. But Courtney Love's manager or whatever said that the next big release will be a "best of the box" a few years down the road. WTF? Why would I want a CD with stuff that's already on the box? She'll probably tack on an extra unreleased song or so to attract the superfans like me into wasting money on it again...
A CD of solo Cobain demos would be nice, as once was promised. Apparently there are a lot of other songs on that Do Re Mi tape reel, and I'd love to hear them...
