Last year, I went to a concert by a California Celtic group named Golden Bough. They had "cassettes" for sale for $45 - actually a flash drive hinged inside a very authentic-looking cassette case. The cassettes had nine albums on the drive, so it was a nice bargain. I loaded the albums onto my computer's hard drive, and never used the "cassette" again.
But it was a fun gimmick.
I have two of your albums, and both are excellent.
