I don't have a good feeling about this set, not as is. As you suggest, there is Dial stuff aplenty on here, as well as (as Allen says) Royal Roost stuff that's been around on Eerest, Savoy, and god knows where else. Some (a lot, iirc) of the live stuff is in bad need of pitch correction, and I'd wager dollars to dougnuts that this Disc 30 is nothing but a compilation of Prez & Bird material released on other CP Records albums.
If this box is straight-up needle/drops and/or dubs of previous releases, nothing that's needed fixing will get fixed.
As far as the original CPR label releases, they're a pretty mixed bag, to put it mildly. A few sets on there I've not yet heard, so there is some selected interest, but 30 CDs? Of needledrops and or dubs?
Not for me, thanks.
