This site also has a number of mailing list archives and other information but is not devoted to progressive music and has little information about more obscure artists. It also has a gopher server. There are Usenet groups solely dedicated to particular progressive bands. Below is a selection to give you an idea of the naming conventions. While mentioning these bands in r.m.p is fine, long, drawn-out discussions of their music should be kept to the appropriate newsgroup.
Some sites have no ftp access, or have ftp access that is limited to local or regional sites.
Fortunately, you can access many FTP sites via email. This section merely provides pointers to central repositories of information wherin you will find endless numbers of other links. Choose the site nearest to you for the fastest access. You can even access music of various lesser known bands. Rather than duplicate all the links here, you can find them on these pages.
