Hi CarolC,I love Bach too. I was similarly transported by a song from the St Matthew's Passion which was performed by Thijs van Leer (flute player who used to be in the jazz/pop group Focus) and a woman with an amazing voice. That was 25 years ago and I was listening to it on a transistor radio the size of a cigarette packet. I rushed out and bought the album and had to wait a few years to play it because, as a poor student, I couldn't afford a record player then. It was well-worth the wait, but it was the only Bach piece on that record.
I have a book of sheet music called The Well Tempered Clavier, which is music he wrote for his wife when she was learning to play a keyboard instrument. It has Minuet in G (which is the music for Unchained Melody(??) by the Supremes), and some other very nice and often well known pieces.
I also love Vivaldi.
