Golden Bough does an annual Christmas concert in Auburn, California, about 15 miles from my home. My wife and I attended this evening, and we really enjoyed it. The did a very nice selection of seasonal music, from Miss Fogarty's Christmas Cake to a very nice version of All Souls' Night.

I bought a "cassette" from them for $45 - it looked like an audio cassette, but it had a flip-out flash drive with seven albums, some bonus songs, some videos, and an audiobook. Clever idea.

Here's one of their promo videos: https://www.youtube.com/watch?v=lAp8EGjTKkM&start_radio=1&list=RDlAp8EGjTKkM#t=73
