Retrogression: Vol 1 is a collection of four tracks, taking themes from Super Mario Bros, Tetris, Punch Out!!, and Ghosts n’ Goblins, all played in reverse.

The album, created by Metroid Metal guitarist Stemage, was inspired by the use of Zelda’s Lullaby, played in reverse, as the theme for Skyward Sword. This got the guitarist thinking about what other game tracks would sound interesting when played in reverse, with these initial four tracks being among the musician’s findings.

The album feature’s the artist’s own musical compositions, played forward and in reverse, for listeners to try out. The music keeps with the NES’ four usable music channels, using two guitars, bass, and drums to create these reversed versions of some iconic game songs.

Retrogression: Vol 1 is available now on Bandcamp.
