Johan, Rasmus and Niklas met and started playing music together in the early years of school, but it wasn't until near the end of high school that they started making plans of forming a band. In the beginning of 2009 Johan asked his friend Stefan who had attended the same music high school as him, if he wanted to play the bass - Coby Core was founded.

In March 2009 they entered the studio to record their first EP called the Surface EP. The core of the tracks were recorded and edited in Fryshuset's Atlas Studio in Stockholm, while the final touches were later on added in Rasmus' own studio.

The recording of the second EP, White Trees EP, commenced in August 2009 in the Molotov Studios of Stockholm. The tracks were then released on the 15th of September accopanied by their first music video to the song White Trees.

Since the start in the beginning of 2009, Coby Core has played on several of the famous stages in Stockholm and also made a shorter tour to Berlin where played together with the friends in Johnny and the Juicebox.

Coby Core's music is inspired from various sources of music, but is better explained as Freshpop. And what Freshpop means, is best explained by listening to Coby Core.
