Formed in 1996 by former Miranda Sex Garden member Katharine Blake, the London-based Mediaeval Baebes have released 7 studio albums, 3 of which have found themselves on the top of the UK classical charts. They have created a unique sound by pulling their lyrics from Mediaeval texts and setting them to original compositions and arrangements, and combining the sounds of classical and Mediaeval instruments with modern instruments.
This is not necessarily my favorite song of theirs (it's so hard to pick a favorite), but I think this was the song that made me fall in love with The Mediaeval Baebes.
