I went to Video Games Live in Vancouver, and since I had gone to see FF Distant Worlds a couple months before that, I wasn't really impressed by the quality of sound in the venue, or the overload of corporate sponsorship, but my friends ended up in the costume contest and had a decent run at it, plus they had Vampire Killer playing near the end in their Castlevania medley. And they had an awesome Megaman medley, too. Not sure if I'd pay that kind of money again especially with stage lights being focused directly into my eyes for so long, but if they performed in the Orpheum instead, or at least improved the sound quality for the back seats and ditch those damn lights, I'd go again. They got the entertainment part down, but the sound quality was pretty dodgey and I paid good money to hear good music.
I'm not sure if I'd be able to enjoy a broadcast on PBS if only because it's a live concert, and I am a borderline audiophile who rages at poor-quality recordings. Live orchestra suffers the most when you lose a lot of the beautiful sound immersion.
