I'm not going to post the link to the article in question because the last thing I want is to give the author visibility, but it's a list of "the 10 biggest douchebags in classic rock".
At no. 1 is Frank Zappa... :s
"Zappa was
a self-appointed authority figure who did nothing but ceaselessly ****, piss and moan without ever offering a single solution or so much as an attempt at constructive criticism".
So there you have it. In his downtimes, the highly articulated, musically gifted, educated, fertile genius known as Frank Zappa apparently could rival with the best of them
parasites uh, I mean, critiques.
