The music of Frank Zappa, whose gonzo brand of rock kept it weird when that phrase really meant something, was so
far ahead of its time it’s still an acquired taste. No matter the electric free-jazz mania of Hot Rats or dead-on ’80s satire of “Valley Girl,” his spiritual influence far outpaced his commercial impact. This year the Zappa estate is celebrating the 50th anniversary of the patriarch’s debut album with sidekicks the Mothers of Invention, Freak Out!; keeping Frank’s laser-brained legacy alive is the one man who knows his dad’s music better than anyone else (except perhaps one person), his eldest son, Dweezil. Despite an ongoing feud with brother Ahmet over who owns the trademark to the copyrighted terms “Zappa” and “Frank Zappa” — recently prompting the name of Dweezil’s group to revert from Zappa Plays Zappa to his own name — Dweezil is forging ahead with a road show titled “50 Years of Frank: Dweezil Zappa Plays Whatever the F@%k He Wants — The Cease and Desist Tour.” Expect nothing less.
