Back on April 15, ELHAE wrote on Twitter, "About 2 years ago I came across a K-Pop group called Monsta X. Soon after I learned one of the members named I.M. was a fan of mine and wanted to work together on something. After all this time, I’m happy to say it’s coming. 4.19.19, you’ll hear 'Horizon'."
Previously, MONSTA X's I.M announced the release of his newest mixtape track "Horizon" featuring a "foreign artist", also hinting at a very different sound from the sound of MONSTA X. Look forward to I.M x ELHAE's "Horizon", coming on April 19 at 12 AM KST!
