Coreign is the progressive hard rock studio band of married composer couple Curry and Reto from Switzerland. The duo doesn't precisely stick to the progressive hard rock genre, they also compose symphonic, ballad, funk, blues, rock and punk songs.

The project was started in 2013 with a different band name, Core, a name that was reflecting the 'inner circle feeling' of Curry and Reto. The band name was renamed to Coreign in June 2016, because so many other bands are using the name Core already. In this rather short period, Coreign made already six albums and one EP, all produced, recorded and mastered in their home studio, and independently released by themselves.
