As there are two performances, this will be a live stream of the second performance. The doors open at 18:00, and the show starts at 18:30. (Japan time, of course. This is 5:00 and 5:30am Eastern)
The participating members will be:
Icarus Watanabe (Vocals)
Kanako Kotera (Vocals)
Masaru Teramae (Guitar)
Inoue Terakazu (Guitar)
Enomoto Atsushi (Bass)
Toshiharu Okajima (Drums)
Noriyuki Kamikura (Keyboard)
Mizuki Mizutani (Violin)
The concert costs 1500 points to view on NicoDouga. That would be 1500 yen. NicoDouga, I believe, has issues taking foreign credit cards, so you will need to go through using a service such as bitcash or webmoney.
The Falcom JDK Band website shows that there’s still another event coming this year.
