I found a link. Wasn't quite what I expected:

Quote:Hard-rock band Hell on Earth said a suicide by a terminally ill person would take place during a concert on Saturday in St Petersburg, Florida, to raise awareness of right-to-die issues.
...
Tourtelot said the band was aiming to raise awareness that physician-assisted suicide should be legalised in Florida.
(Emphasis mine.)
Still creepy, and the whole "raising awareness" thing may well be after-the-fact bluster, but that's a little different from the image I had before I found the link. Hmmm.
Awareness-raising of this issue is good, but I can't imagine how this would actually be helpful in any way. And given the band's track record (grinding up live rats... that raises awareness of what?) I really suspect they were more like, "Dude, wouldn't it be totally bitchin' if someone, like, DIED on stage?" and then figured out how to go about it.
