Gramophone review and the availability of the Multi-track Master files

Posted by Robert Douglass (Creator)

Feast your eyes on this interview with Kimiko Ishizaka and review of the Open Well-Tempered Clavier in Gramophone Magazine - the most important reviews publication in the classical music industry. This is PAGE ONE of the current issue, which means the Open Well-Tempered Clavier is now officially famous. 

Here are some quotes:

"Ishizaka plays the 24 preludes and fugues with impeccable taste and technique, finding many levels of musical meaning even as she brings utmost clarity to the multiplicity of textures.

"She scales her Bach to the rhythmic, structural and sonic needs of the music, without touching the sustaining pedal. Her articulation runs the sensitive gamut from cushioned to bitingly crisp.

"It is the fugues where Ishizaka goes furthers in demonstrating how intimate she has become with Bach. Each line has a transparent place in the scheme of unfolding things, and the pianist seems to take enormous pleasure in weaving together all of the miraculous strands.

"Playing in darkness has led her to illuminating views of Bach."

It's safe to say that reviewer Donald Rosenberg really likes this recording =)

Multi Track Masters

The Open Goldberg Variations and Open Well-Tempered Clavier projects are groundbreaking in their approach to sharing the materials produced. Today we are going to do something even more radical than ever before, and provide you, and the world, with the 11 master files - one from each microphone - that were used in the mixing and mastering of the Open Well-Tempered Clavier recording.

Each file is the full recording from the point of view of one microphone. With these files, every recording engineer and student of sound can create their own mix of the recording. You can compare the sound of different microphones and different microphone positions, and create balances that you possibly like more than what we released.

The fact that these are 96K/24bit tracks makes them an audiophile dream. For example, you could mix your own 5 channel surround sound version. And these files, just like the mixed and mastered recording, are being released CC0 - available for all use.

Here is the link. Be warned that it is 3.2GB of files, so if you don't actually have a use for this, you may want to skip the download =)

The Open Well-Tempered Clavier, 96K/24bit multi-track masters.


Microphone list:

  • 01 and 02 : DPA4006 
  • 03, 04, 05, 06 and 07 : Neumann M50 (05 and 06 not pictured in the photo)
  • 08 and 09 : Neumann TLM50 
  • 10 and 11 : Neumann U6
  • Other microphones shown in the photo were not used in the mix.

Thank you, Anne-Marie Sylvestre, for providing these files and the description of the microphones.

Here is another link which many of you have been asking for - all of the MuseScore files in one Zip file.

Enjoy! And tell people about this unprecedented cultural treasure that we have collectively created.

      Thanks for that - although you may find tetrads more imprecationally efficient. Downloading now - looks like it'll take about half an hour! :)

      Very good, Paul Sampson. We're looking at > 18 GB for the masters. They're on the way.

      Oh, double sharp diminished triad! I uploaded the wrong damn file. Look for an update tomorrow with the right one. :(

      This zip appears to contain 48 stereo wav files of some mix, I'd guess the master mix. 3.2 GB sounds about right for one set of high quality sound files. I guess there are still the 11 sets (presumably about 1.6 GB each, zipped) of 48 mono wav files from each mike to come?

      I can't use the master files myself, but I do appreciate that you make them available. Thanks!
