Duality is the debut extended play by the South Korean rapper I.M. It was released by Starship Entertainment on February 19, 2021. The digital EP contains five tracks including the lead single "God Damn".
In January 2021, I.M announced that the solo work he had been preparing in 2020 will be released as his first solo album, rather than a mixtape release, and an intended release later in 2021.[2][3][4][5] The EP was released digitally, rather than as a physical album, to avoid restrictions on its sales by an explicit rating.[6]
Its physical was released in LP version on April 20, 2023.[7]
The tracks on the album were noted for all being themed around "duality" (二重性).[9] I.M was noted for "showing versatility as an artist" and "expanding his musical style when compared to his work in Monsta X".[10][11] That the difference of his musical style in Monsta X to his solo work, as noted by Ruby C for NME, it was "part of showing the theme of the album" along with the "emotion and delivery of the tracks".[8]
