Here's a quite nice webpage I found covering the subject of dead rock artists.

That's on the starting page:
Welcome to the club rock stars are dying to get into. Rock and Roll may never die but rock stars do! This site is a list of dead rock stars, dead people associated with rock and dead people whose music helped influence and create rock (which I feel includes Jazz and Country artists), sorted by the date of their demise. This is a tribute to them.

It seems some things are missing yet, but what I have seen is alright. Enjoy!
