Hüsker Dü is indeed pretty tight. I never could get along with any of the subsequent Mould or Sugar, tho. I wouldn't exactly characterize the Dü as 'underrated' either, especially if you were alive and kicking during that time. Ever hear the theme to the Daily Show when Craig Kilborn was still on it? -->Mould.
Anyone who considers themselves fans of the aforementioned or of Burma, MinorThreat, SonicYouth, Dinosaur, Minutemen, all things SST, etc. should really check out a book called
Our Band Could Be Your Life. It's about the underground indie scene of the '80's. Required reading if you lived it or if you live for it.
