The news that Frank Zappa’s children are feuding over the rights to the rock star’s music was shocking. But Dweezil Zappa (inset) says he’s been dealing with the issue for more than a decade. “I know people are sad and angry. They can’t understand why it’s happening,” says Dweezil, whose band plays at the Brighton Music Hall Saturday. “But for me, I’ve been going through this for a long time, so it’s not a completely raw nerve.” Zappa announced last week he’s changed the name of his tribute act to his late father from Zappa Plays Zappa to Dweezil Zappa Plays Frank Zappa. The reason? He said the Zappa Family Trust, which owns the rights to his father’s music and is overseen by two of Dweezil’s siblings, Ahmet and Diva, informed him that the name Zappa is a trademark owned by the trust and he could be sued for copyright infringement for playing songs without proper permission. Dweezil said his mother, Gail, who died last year, was “the one who began creating the obstacles” by charging him a fee to use the name Zappa Plays Zappa. “And it wasn’t a small amount of money,” he says. Dweezil said his mother also repossessed 14 guitars that were left to him after his father’s death, and his siblings now plan to auction them. (Frank Zappa, a prolific composer and songwriter who recorded more than 80 albums, was 52 years old when he died of prostate cancer in 1993.) “This whole thing is just unfortunate,” says Dweezil, who’ll be playing songs from his new album, “Via Zammata,” at Saturday’s show. “I’ve been doing Zappa Plays Zappa for 10 years because I want people to experience my dad’s music, to have the opportunity to hear it performed live.” He said he plans to post something online that lays out his side of the Zappa family feud. “For people to believe what Gail was doing, as far as protecting and nurturing Frank’s legacy, it turns out to be quite a different story,” says Dweezil.
