Query: AKA MAGIC SAM? KEEP IT THAT WAY...BAD R.T. CD

THIS IS ONE OF MY WORST SLIDE GUITAR CDS. IT'S ALL INSTUMENTAL. AND, ALTHOUGH SOME OF THE 18 TRACKS SHOW GOOD SLIDE PERFORMANCE, ON THE WHOLE IT'S FAR FROM RON THOMPSON'S BEST WORK. REAL FAR. I HAVE SOME OTHER RON THOMPSON CDS..."JUST LIKE A DEVIL" IS ONE. IT'S REAL GOOD STUFF. BUT THIS ONE....WELL, I READ THAT HE WOULDN'T EVEN AUTOGRAPH THIS CD. I ALSO READ THAT IT WAS "UNAUTHORIZED" BY HIM. HERE'S A GOOD TIP FOR NEW AND UPCOMING ARTISTS: IF DON'T WANT SOMETHING YOU CREATE TO END UP IN THE PUBLIC'S EYE (OR EAR)LATER ON IN LIFE....DON'T CREATE IT IN THE FIRST PLACE. WANT TO REALLY DIG RON THOMPSON'S ARTISTRY? BUY "JUST LIKE A DEVIL". THAT....YOU'LL DIG. JERSEY SLIM
