This is a demo of "The Jammer".  Most people have heard of Band-in-a-Box.
Jammer is similar but goes quite a bit further.

The file JAMRDEMO.EXE is a self-extracting archive file.  It must be
extracted into a directory called \JAM20.  Like most demos of this
sort, it does not have the ability to save any of the work that you
have done.
