NEDERLAND, COIn spite of your insistence that you are not into Frank Zappa, avid fan Roger Von Lee believes that you would change your mind if you heard the right album. 'You're prejudiced, because the only Zappa you know is 'Valley Girl' and 'Don't Eat The Yellow Snow,'' Von Lee told you Tuesday. 'Seriously, you need to check out Hot Rats or Absolutely Free. Zappa and the Mothers were at their peak, and Zappa's jazz-rock fusion experiments predate Bitches Brew. That'll totally convince you that Zappa's the shit.' Von Lee added that if those two don't get under your skin, he can recommend another 15 to 20 albums that will for sure.
