I know you asked for CD but there is an LP version that really should be heard. E> Power Biggs has been mentioned, one particular album set he put out has him doing an organ tour of Germany and Holland, playing on organs built by APR SCHNITGER(1648-1719) organs Bach himself might have played on. The sound is quite different from modern organs, lighter, airier, higher, if you can get a hold of it and have it transferred to CD you will be quite amazed. I know I was. It is on Columbia Stereo M2S 697 or Mono M2L 297.
Sorry for the digression but it should be heard to hear what Bach wrote/composed as he would have heard it.
