The Christy/Portnoy drum battle was cheesy as all hell, but I had a huge grin on my face the whole time, and anything that gives me a legitimate excuse to yell SLAYER! at a DT show is fine by me...
You can just buy the DVD when it comes out. The only difference is that you'll have a menu screen, and you'll be watching it on your tv from the point of view of multiple cameras. And you won't be able to hear the amazing acoustics of Radio City.
True; it will be a lot more affordable than actually going... At least then I could start some sort of fundraiser for myself and go door to door to earn money for the DVD...or something like that.
