that and the fact it would probably ruin Glenn's immense credibility with those bands and leave him booking Winger & Nelson as headliners at PP6.
But there's always a possibility to get 'limited edition' supported releases by the bands/labels that wouldn't be 'too costly'. Example, copies numbering no more than 500, the royalties are very very low. And as we all know, 500 would cover all us Gold Badge holders
as well as those elite lucky few that could snag a copy. Also 500 is a number easily produced at a decent discount at production places. I'm also pretty sure 500 of us would gladly "pre-pay" to special order these things. Hell, they don't even have to be pretty-packaged to keep costs down.
If it were a possibillity, I wouldn't see why every band's show at every ProgPower wouldn't sell out in it's entirety, even "less popular" ie; Mercenary, Silent Force, REdemption, etc.. although a more modest # of 250 to see how they would go would be a route I would go.
All that said, it would be a nightmare to get a "compilation" dvd made because of all the different labels, that just won't happen. You'd have to go after each band and most likely those individual performances.
