This is the Festa part of the 2 disc set.
Likely due to Hirano Aya and Mizuki Nana being part of the "White Album" team, it was hard to get good tickets. But if you're willing to throw money at the problem, it can be solved, and so I got a pretty good seat for both events. I think I spent over $350 for the tickets, although that includes two seats each. Obviously, one set of them (not so good seats) were wasted.
I enjoyed it. It was the first time I got to see a bunch of seiyuus, in person. And I got to hear Suara singing the normal version of the Powder Snow, live. Hard to beat that.
Hirano Aya and Mizuki Nana did not sing any songs during the event, which is understandable. However, there was one sample video (White Album Ending) with Nana-chan's vocal. Obviously, it wasn't a live singing, nor was it a full version, yet that video is cut from the DVD version. Considering how technically crappy her management's treatment of her music is, they sure are uptight about it. Whatever.
I had a good laugh because I got that question right! This had to be a guess because the question is about the future event that hasn't yet happened. The first line was Eruruu calling out for Hakuoro-san.
