Monsta X’s rapper I.M (Im Chankyun) released his first mixtape Thursday (April 18). The two-song Horizon was released through digital music platforms, and fronted by a title track of the same name featuring Elhae.

“Horizon” is a chill take on melodic alt R&B, with I.M putting forth calmer vibes than are typically associated with K-pop boy band Monsta X, where he more generally serves as an agressive, gruff toned rapper. Paired with Elhae’s smooth verses and reverberating tone, the track is a contemplative and effusive love song.

I.M and Elhae, who have worked on the collaboration for over two years together according to a press release about the song, both appear in the music video for "Horizon." Fittingly for the atmospheric nature of the song, the clip features I.M rapping as he reflects on the relationship amid vibrant Seoul scenery while Elhae appears as a floating head in futuristic CGI setting surrounded by classically inspired columns, a recurring element in the music video.
