First off: Rock isn't dead, it's just in hiding and you have to look harder to find it.
That said, I am of the grunge era (and place, I grew up in the Seattle area) and I looooved it. However, I am going to go with punk because of the more-often-than-not political aspect, and being an angry young individual myself who feels there is something very wrong with the world today, punk has given me my favorite form of expressing that anger. RISE AGAINST in particular just hits all the right chords within me and one can easily back a politically charged punk band as a "way of life" more than anything else. I follow RA, and all who came before them/influenced them, for eternity with a fist raised high into the night air.
