I have what some would call a very eclectic taste in music.  My I-Pod contains everything from Gregorian Chant to Bon Jovi.  One of my favorite artists is the 1920’s gospel blues musician Blind Willie Johnson.  Some of the most powerful gospel songs I have ever heard have come form this man.  Here is a video of one of his songs; you may want to turn up your volume to hear all of it.  If you like it, his complete anthology is on I-Tunes for a reasonable price.  Enjoy!
