I don't lump DIY Fugazi in with big label Green Day. Nonetheless, nice to see a post about Hüsker Dü. I loved the wall of sound that was Candy Apple Grey.
As a teen just getting into hardcore in Moorhead, MN in the mid-80s, it still kills me that it took a penpal from Brisbane, Australia to fully appreciate Husker Du. It's a damn shame I never saw them when I had the chance...although seeing Grant Hart at the Funhouse followed shortly thereafter by a Bob Mould show at the Showbox a few years ago was pretty amazing. It's criminal that Bob nearly sold out the room while Grant played to a nearly empty house.
@ 7, I think Bob Mould has always been better at selling himself. When the Huskers broke up, Bob got himself another major label deal while Grant Hart had to go back to SST (which was beginning to collapse, although nobody knew it then - but the fact that their best bands were all defecting to majors did make his return look like a regression of some sort). That pretty much was where their careers diverged, even thogh Hart remained Mould's songwriting equal.
I completely agree about Hart being Mould's songwriting equal. Much of Hart's solo material is amazing. As you may well know, Hart's had his share of struggles physical and otherwise, which I'm sure has made a difference in the outcome of their careers (in addition to label & promotional issues you mentioned).
