The internet has just uncovered a full-length album that KJ released back in 2012 called The Third Room featuring songs written by KJ himself.
The tracks are a mix of rock and pop, with KJ providing vocals as well as some mean guitar.
The album description describes the vibe as: "The album reflects modern free-flowing fusion-rock beats with a hint of Latin rock in some tracks."
Believe it or not, the album has been under our noses this whole time on Apple Music so go ahead and give it a listen!
If you don't have access to Apple Music, however, the individual tracks are also available on YouTube.
Here's a little taste...
