Sea of Black Festival in Burgas
Sea of Black staged free, open-air metal shows at Burgas's Summer Theater, built around Bulgarian and regional extreme and heavy metal acts rather than international headliners. The festival announced a break starting with its 2025 edition, and its official domain now redirects to a domain-sale page, so its current operating status is unconfirmed as of this writing.
A domain-parking notice now sits where Sea of Black Festival's own website used to be, a blunt data point for anyone trying to confirm whether Bulgaria's Black Sea metal gathering is still running.
