An article on the Canadian violinist and ex-Chanel model Leila Josefowicz:
Now she's preparing Adams's latest violin work, The Dharma at Big Sur, which mixes Eastern influences with West Coast styles and ideas. 'I'm quite familiar with the kind of jazz sounds and the improvisation that John has written in, or rather not written in, and I feel strangely liberated playing this kind of stuff.'
It's written for a six-string electric violin, a Violectra, that Josefowicz had made to her own specifications in Birmingham, its shape identical to the fabulous Guarneri 'del Gesù' instrument she plays.
Wikipedia says she was born in Canada but moved to California at a young age.
