Anyway I feel it should have been on 2 discs instead of just one for the best possibly qualityI’m confused -- assuming we are talking about "Turn up the quiet", her current release? My copy is on two discs (3 sides, side D is blank) and 17’ or so per side.
While packed in card sleeves it cleaned up nicely. There’s a fairly high level of groove rush, typical of current pressings, but not noisy. It is cut very hot however which may cause problems with some setups. In particular I got some intermittent (3-4 times on a side) distortion on left channel peaks, but nothing too objectionable
Recording wise the best thing about it is the acoustic bass which is reference quality. The vocals are overly close miked which is fine albeit a bit too breathy for my tastes. All the other instruments are in band mode which sounds fine, although the recessed piano is a bit of a surprise for a DK disc!
All in all a nice record and my copy (from Acoustic Sounds) had no issues.
With regard to maximum length on a side it also depends on the material. Lots of very dynamic passages will take up more real estate, while a disc of quieter music can easily sound fine at up to 30’ So all in all it’s very hard to have a hard and fast rule I’m afraid
