Grant Henry, the guitarist better known as "Stemage" who is the founder of Metroid Metal, has released a new album where he plays classic game music backwards. Retrogression Vol. 1 features classic music from Super Mario Bros., Punch-Out, Ghosts 'n Goblins and Tetris played in reverse, along with the reversed version of those reverse tunes (which is to say, the original non-reversed versions). All songs are played with two guitars, bass and drums, to mimic the four-channel sound chip of the original NES.
"Most Zelda fans know by now that the theme song from The Legend of Zelda: Skyward Sword is actually 'Zelda's Lullaby' in reverse," said Henry. "Retrogression Vol. 1 is a musical experiment following this same idea, keeping the arrangements clean with just four instruments similar to the four usable channels on the NES: two guitars, bass, and drums."
