If a role-playing game is about a bard, or is at least titled for one, then some care must be shown to the musical accompaniment. The Bard’s Tale 4: Barrows Deep, launching Sept. 18, brings a robust original soundtrack, but as its forebears are more than 30 years old, it couldn’t really look to their chiptunes for inspiration.

InXile Entertainment is giving its dungeon crawler, successfully Kickstarted in 2015, a celtic theme, so the studio’s search for musicians logically centered on folk singers. They found a choir and recorded several gaelic songs, some of them hundreds of years old.

Producer Ged Grimes (who the chyron helpfully notes is a member of Simple Minds) introduces the singers and musicians. More than 100 pieces comprise The Bard’s Tale 4’s soundtrack.

InXile also announced that the signature torch from Darkest Dungeon will feature in the game, thanks to Red Hook Studios and users meeting a wishlist incentive goal. InXile said that the retail price will drop to $34.95 and then $29.95 respectively if 300,000 and 500,000 players wishlist the game, respectively.

The Bard’s Tale 4 is being sold for PC on Steam, GOG and Humble. The game will launch for PlayStation 4 and Xbox One as well.
