Bach: Music in the Castle of Heaven

I found Bach and his cantatas in Spring this year, and have been following the cantata cycle since then, listening to the “correct” cantatas every week. I've been focusing primarily on Gardiner. Getting this book was an obvious move, in order to find out a bit more about Bach. I certainly got a rather large pile of information. Interesting, mostly, bit heavy on the musical theory at times. I don't understand music theory, so I didn't understand large part of Gardiner's music terminology, but despite that, this was an interesting description of Bach's life and his work. Highly recommended, if you're interested in the topic. It's a heavy book, though, 560 pages of content with a tiny font.
