I am under the impression they are. Indent (on CD) finally gives you the feeling you are listening to a real piano.
From their website:
Celestial Harmonies, div. of Mayflower Music Corp. has been in business since 1972. The company is affiliated with German music company E.R.P. Musikverlag Eckart Rahn of Berlin.
E.R.P. has been in business since 1968, making it one of the oldest, if not the oldest, independent music companies dating from the 1960s, still being operated day-by-day by the founder, with no change of ownership and a catalogue of app. 8,000 copyrights held, both recordings and compositions.
For Indent it says in the booklet: "Analog remastering by Jack Ashkinazy, CBS Studios, New York. Digital remastering by Frank Jacobsen, Bremen. Originally released by Cecil Taylor on Unit Core Records. Eckart Rahn supervised the re-issue from the original recording made on reel-to-reel tape at 7 1/2 i.p.s. halftrack stereo to vinyl and later CD."
There are both CD and CDr entries for Poschiavo on Discogs. I contacted the label by email last month, and they explained a very small number of review copies were released on CDr while they were waiting for the CDs to arrive from the pressing plant. By now these should all be off the market. I ordered through Amazon and got a real CD. For Indent no CDrs were released.
