further re: Bloodhag, I found this interview with them. the interviewer covers films for a local paper and liked the tour video.

Q: Tell us what Edu-Core is. Did you coin the term?

A: Yes, I coined the term as soon as we formed the band, seven years ago. Although KRS-ONE coined the term “Edutainment” in reference to his music, but we’re different since I don’t give a rat’s ass if you’re entertained.”
