Drummer/songwriter for one of the most influential punk bands of all time, Husker Du. Two of their albums, Zen Arcade(an 80 minute, 23 song concept album), and New Day Rising are usually ranked on lists of best punk albums ever, and I like them a lot.
To show their influence: billy joe of green day and dave grohl(talking about nirvana) have said their bands wouldnt exist without husker du. It could be said the grunge explosion and grunge itself never attains the heights it did without husker du, but thats just my own speculation.
