I think Eddie Van Halen R-E-V-O-L-U-T-I-O-N-I-Z-E-D rock guitar in the late 70s. AC/DC and VH kept ROCK honest when a lot of other bands were wearing skinny ties and Ray-Bans.
You say they "revolutionized" rock. I agree, insofar as they lead the charge back to the arena rock excess against which punk rock had rebelled. It was as if punk rock never happened. Now admittedly punk rock very soon spawned excesses of its own, e.g. Mohawks and razor blades, but that was much more the case for punk rock fans than for the bands themselves.
With all their excess can you honestly blame me for poking fun at Van Halen? I mean how can I not? Freddie Mercury himself would have been proud of their outfits.
And I really do prefer the skinny tie Ray-Ban wearing look to that sported by arena rockers:
Come on! How could I not?
And the music of both Van Halen and AC/DC? To me both bands just sounded like Led Zeppelin imitators who didn't know the first thing about the blues.
