a concert DVD is a concert DVD, no? or are we discussing the highly intellectual ideas of NIN's AATCHB vs show off purposes of MM's GGG?
a concert dvd is a concert dvd. aatchb was made up from the setlist, best audio takes and best video shots (according to the feel of the band) from the usa tour to give the effect of "being there". it also was all about quality, so the bonus material is shit. manson's vhs/dvd releases are made more for the shock value (lookie, i have a shemale pissing on the floor in my room, protests, that kind of bogus rock star shit) rather than artistic perfomance.
so the outcome is this: aatchb and byit are concert dvds because their main focus is the show. ggg dvd is more like a "tour documentary", so you can't call it a concert dvd. but you can't even call it a proper tour documentary either. it's just a collection of all the horrendous stuff that they had "backstage". big deal.
also why am i bothering with this nonsense?
