Dweezil Zappa can't stop talking about his late father. "Frank's music just needs to be heard," he says. Alongside brother Ahmet and several of Frank's former sidemen, Dweezil now re-creates his dad's music on the Zappa Plays Zappa tour, featuring material from the elder Zappa's mid-Seventies heyday. "People tell me that the show made them feel like they were back in high school, like it was a time machine," Dweezil says. Since forming Zappa Plays Zappa last year, Dweezil has gone to great lengths to expose his father's compositions as a kind of panacea for the malaise infecting the current popular music scene. "Frank came in an era before all of the corporate madness became a part of the entertainment business," he says. "In my father's era, it was possible for an artist to do new and different things, [and] that stopped happening when things were corporatized." Even Frank's "hits" — such as "Don't Eat the Yellow Snow," "Valley Girl," and "Dancing Fool" — were contemptuous jabs at popular society, and by fusing amazing instrumental dexterity with a truly perverted sense of humor, he remains a singular figure in American music. Dweezil, naturally, is his biggest cheerleader: "I don't have to say anything about Frank's music, 'cause it speaks for itself."
