When I was still working, some fellers in the office played some alleged "blues" recording which sounded like acid rock to me. The kids were flabbergasted when I told them that blues was invented by musicians who did not have electric instruments. I played for them some of my recordings which I had taped from 78's & LP's. Some were even-dare I mention it-not even guitar! They had never heard anything close to Blues befoe. One kid was in a "Blues band." He had his band learn several songs. I had to teach the guitar riffs & some of the progressions to him, & the piano parts to the keyboard player. They performed them at the local Blues Crawl contest & won the top honor.
