your ultimate posthumus rock band...horns included

i guess one part of the debate would include either j. bonham or k. moon.....

Fishbone, not quite classified as Rock.
IMO, horns combined with a Rock band automatically preclude that category. Furthermore, there is no true "ultimate" in my interpretation regarding anything.

Good call on Chase. Their last album, "Pure Music", is definitely worth a listen. Bill Chase, I understand, was the high-note man for Woody Herman's Thundering Herd before forming Chase.

And how about Spirit? Randy California drifted away on a surfboard and wasn't heard from again.

The REAL challenge would be posthumous rock group ONLY horns.

In that vein, for me it is a toss-up between ...

Chase ... big song was 'Got to Get It On'. Some of the highest notes hit in the horn solo.
Electric Flag .

As for the ultimate rock group, it only gets interesting after the Beatles, Led Zeppelin, Rolling Stones, Byrds, and Jimi Hendrix Experience are eliminated.

My favorite posthumous rock group is R.E.M. Hopefully, none of them will be deceased for a long time, but they have disbanded. I miss them already!

So who's in yours?
