I'd never heard of "Bardcore" until, quite by chance, I came across the Youtube channel of a lady calling herself Hildegard von Blingin' (an obvious play on the medieval abbess, musician and composer, Hildegard von Bingen). She has this to say:
Bardcore for the discerning clergyman, noble, or muck-gathering peasant.
I am a Canadian singer/illustrator who started making Bardcore in the Spring of 2020. If you're new to Bardcore, it is a pastiche genre that takes modern songs and makes them "old-timey" through the use of Medieval and Renaissance inspired instrumentation, as well as Shakespearean-ish lyrics.
Unless otherwise credited, the majority of the instrumentals were created by me. They feature a mix of virtual and real instruments, including the Celtic harp, Irish whistle, and recorder. Several videos feature my brother, known here as Friar Funk.
I've picked three of her videos at random to illustrate the style. Where necessary, lyrics may be found on the track's Youtube page. If you know of others who are performing similar music, please let us know in Comments.
Not knowing the Bardcore genre at all (if it can be called a genre), I don't know yet whether I really like it or not: but it's certainly a different take on medieval and modern music. I'll try to find more of it, to give it a fair shot. What do you think, based on these few samples?
