The performance’s programme seems to have been confirmed.
I did not think of things like being able to listen to the orchestra of Sonic and NiGHTS, so I am really happy. Moreover, they will perform us even Feel the Magic and Burning Rangers.
The compositions of NiGHTS were recorded in orchestra, but it was my first time doing the orchestra recording in a game, so it is very memorable. That is 20 years ago.
The emcees will be the SEGA Hard Girls, but Center-sensei isn’t invited, is he? … Though the leader of the Rub Rabbits is okay also, isn’t he?
