Speaking at the Atari Live event that's taking place in London this afternoon, Mizuguchi said very little about his new game other than promising that it will be a completely new experience.

Originally released on PlayStation 2 and Dreamcast by Sega, Rez was a critically acclaimed on rails shooter. What made it special was the way players created sounds as they shot foes. In addition to Rez, Mizuguchi was also responsible for Space Channel 5 and Lumines so the fact that he's creating a music game exclusively for Wii is exciting news.
