If you want to get into it, start by putting the released version on repeat and listen to it a few times in a row. To start, focus on Kurt Cobain’s voice, specifically where it ‘sits’ in the mix. Then, switch to Steve Albini’s version.
When I hear Steve Albini’s version, Kurt Cobain’s voice is less pronounced. What do you think??
If that helps, I can point out more differences. Or, maybe you can point out some you hear?
To me the differences matter much less than the fact that after about a minute and a half you've basically heard the whole song, and then I just get bored.
