Along with each artist or group, I have a link to CDnow's page about them. Though CDnow is not a Christian site, they have biographies, sound clips, and lots more for each artist or band. They even have a way you can buy CD's on the web.
If anyone knows of another place I "should" be using instead of CDnow, please let me know and I'll look into it.
If you have a page that I don't have and you would like me to list, please let me know and I'd be happy to include it (with a reference to who I got it from, if you like.)
