Inside the Zappa Family Feud

It's soundcheck time at the Capitol Theatre, just north of New York, and Dweezil Zappa is leading his band through the songs of his father, Frank. Dweezil, 46, has been regularly performing his dad's music for a decade, but his current tour is stranger – and more tense – than any before it. Unplugging his guitar, Dweezil looks out at the empty hall. "Sometimes people in the crowd yell things out, so I talk about it onstage," he says. "I feel like people are choosing sides."

This should be a year for honoring the legacy of Frank Zappa, who died in 1993. A new, acclaimed Zappa documentary, Eat That Question, is in theaters, and a series of deluxe reissues and archival releases just hit shelves. Dweezil's tour features songs from Frank's landmark debut, Freak Out!, released 50 years ago this summer. But instead of celebrating, the four Zappa children are locked in a drama that has bitterly divided a once-close family and exposed its quirks. "I was hoping to keep the fact that we were a Grey Gardens family a secret," says oldest daughter Moon, 48, an actress and novelist. "Oops!" via RollingStone
