Wow, I'm feeling lucky because the setlist of the day I was present is my favorite so far. Although I loved all the performances, for a DVD I would change in the land of twilight under the moon, liminality, hanamori no oka and eternal blue.
I would love to have either key of the twilight or winter replacing Hanamori no Oka. March is a good option too, like ritardando said. awake is another one I always wanted to watch the live version. Materialise is a must! Xenosaga is something I'm really looking forward to as well.
But you guys will be in love with luminous sword and Kimi ga Ita Monogatari if a Blu-Ray is released, so it will be awesome anyway.
