IGN have put up a new preview of Rez HD up, including a few choice quotes of Tetsuya Mizuguchi himself:

"If you listen to the sounds, the music, you can feel the color," Mizuguchi told IGN as he explained that Rez HD is just as much an experience as it is a game. As is the trademark of Mizuguchi and Q Entertainment, the sounds and vibration are intricately woven into the gameplay. Shoot down an incoming enemy and you'll add effects to the trance music already playing, weaving new layers of sound into the game as you play.
