So steelydave.....whisper into the ears of Mr. Dutton that The Best of Nina Simone might be a great contender for a D~V SACD upgrade. Would certainly satisfy his existing fan base as well.
I'm sure he's aware of it, I think it goes without saying that D-V have an excellent grasp of what is available in quad. I don't know what the status of Simone's estate is today, but following her death her estate and her former attorney were mired for years in lawsuits and counter-lawsuits (it appears some of which have been resolved) and that kind of thing makes licensing impossible since no one can agree who owns the material in question.
I think D-V's been really good so far in the amount of jazz, R&B and blues-based quad material they've released thusfar (much to the chagrin of some rock fans) so I doubt they'd pass up Nina Simone if the opportunity presented itself.
