The March 2006 issue of French "Guitar Collector" magazine included
a huge Zappa special.
The magazine also included a 12-page guitar style study by Max-Pol Delvaux, including audio fragments on the added CD.
The audio discs presents 25 audio examples. No Zappa pieces, but Zappa-eque
licks and musical fragments showcasing Zappa's guitar style.
Max-Pol did a great job. It's like one big puzzle.
