Ssamzie Sound Festival was an annual indie music festival held in South Korea from 1999-2014.

The first version of the festival was held in Yonsei University, with 20 local bands performing.

The festival started out as a free one-day-festival, but as the festival got more attention it grew.

The "Sumun Gosu" was a gateway to success in a career for Korean indie band.
