temporarily, yes. but how much is of lasting significance? how did raves affect politics or social life beyond the confines of the raves themselves?
a social revolution is something that broadly changes social life, or at least attempts to broadly change social life, outside the confines of itself. raves were a scene that many parts of society felt threatened by, but mostly for what was going on within them (i.e. "won't someone think of the children?!"), not for their effect on politics or mainstream, as with the hippie movement and reggae in jamaica. at least, that's how i've come to see it after gaining some distance from it...it did seem a lot more revolutionary at the time.
