Ok, you're right, the Impro-Jazz is bootleg, not pirate. My bad (2nd time today...yikes...)...
As for WestWind, IIRC they would release some things that had been legitimately releases, but Moon? Maybe at the tail end, one or two things...no need to debate the whole "bootleg" thing again, almost everybody has some, one way or the other (I know there are a few Pure Souls out there), and no, I really don't think that bootlegs should be nominated for "legit" awards, but some of the very best music I've ever heard has been bootlegs, and if it was all about royalties and such, then we need to get "universal" on public domain laws and such, and ain't no way that's gonna happen... We all love our Chronological Classics and such, but there ain't no royalties being paid there, never will be, never will have to be. Objectively, those things are more like pirated items than bootlegs, and pirating is something that is worse than bootlegging in my own heirarchy of Bad Things To Do To Other People's Stuff. But...it's legal! And we do love 'em! And nobody gets paid!
All I'm saying is that any indignation over a boot being nominated for a "formal" award is certainly justified. Any indignation that such things exist and are actually "popular" is either feigned or hopelessly naive. Also to add that in these days and times, if you want a bootleg and actually have to pay to hear it, you're just not trying hard enough...
