When Zwan released their only album; Mary Star of the Sea a version of the release included a bonus DVD called “For Your Love”.
This DVD would included a number of interviews along with a number of unreleased tracks of live, and studio recordings. Which when (not if) their is a release of Zwan more materials we can definitely expect some quality unreleased tracks.
