The size of the file for the Massey concert is about 640 MB! The recording lasts for about 1 hour and 51 minutes. That is why the file is so big. The recording is already condensed for download into shn files. Once you've downloaded the file, you must convert the file to wav files. Then you can burn it to a cd like you would any other wav file. I used the program found on this site to convert my files:

It's a good and simple program with no unwanted spyware or anything like that.
