The local Classical Station has recently started broadcasting Sunday Baroque, which, though I've never yet managed to catch it in its entirity, or anything even remotely near its entirity, I consider a huge treat. This past Sunday the airwaves were exquisitely alive with a piece called "Folies d' Espagne," by a group called the Palladian Ensemble. If you go to their record label's website, you can hear a tiny clip of the piece, the very last selection on the CD. There are several other impressive versions to be heard on YouTube, my favourite, so far, being the one below, a solo by flutist Mario Caroli, but having heard the Palladian Ensemble's arrangement first, I miss the lively interplay between the recorder and the viola da gamba.
Now, veering off in an entirely different direction, here is a very intriguing article that is only related because the link was posted on Sunday Baroque's Facebook page. . .and it does mention Bach a couple of times--and the Theory of Relativity a couple of times. It's about Einstein's musical side, which was considerable.
