Progenies of the Great Apocalypse by Dimmu Borgir (a really great song and video) got the entire 2nd verse chopped for video. I think what it boils down to is something very simple that Shagrath (vox) said in an interview recently, namely that you really have to develop an ear for black metal, you cant just start listening to it out of nowhere.
So you got these kids watching headbangers ball or whatever, and they've got A.D.D. as it is, cant pay attention to shit for more than 2 minutes these days, let alone some cookie monster singer clad in facepaint and Halford leather...
Anyway, I guess it's smart for Dimmu to cut to the melodic Vox in the middle earlier while they still got the audience's attention. The objective of the video is to lure the audience in toward the band, and songs that have less are easier to follow, hence, lets cut that shit out and make it (in the words of Robb Flynn several years ago) "Commercially Viable."
All that being said, I think what we are really discussing here is ART vs. PROFIT. At which point can something still be considered art, despite having been cut, chopped, edited, etc. enough to change it into something "commercially viable," something profitable?
On the one hand, you could argue that it's ok to raise the vocals or to cut out a verse for a video or radio edit because the bottom line is that it will get the band better quality exposure, which is good for everyone including the band, the fans, and the media fuckers.
On the other hand, you have to evaluate what's REALLY going on. By definition of what metal is, at least in most people's eyes, it is totally hypocritical to edit a metal song. The whole point of metal is to stand up against shit like that, yet how many bands fall into that trap of "well, we're really good musicians, and we've got a solid following, let's try to take that direction and who knows maybe we'll get lucky and get famous." I'm not gonna name any names, but we all know what happens when bands try that shit and the metal gods don't let it happen. Two albums later they're broken up, or at least they should be.
Ok, sorry for the rambling...by the way, does anyone have a link to the remixed I, Voyager? I am dying to be able to hear what the hell the guitars are actually doing on some parts, which are too muddy on the cd.
