Last night in the UK we had number 3 of Howard Goodall's "Big Bangs" in the history of music - the development of equal temperament. I felt this brought the series back on track after a weakish programme on opera. It prompts me to ask if anyone knows of any resources (CD, CD-ROM or website) where it is possible to hear the same piece(s) played with different tuning systems for direct comparison with each other?
