From Guitar World...
"Janie Hendrix, CEO of Experience Hendrix LLC, the Hendrix family-owned company entrusted with preserving and protecting the legacy of Jimi Hendrix, noted, 'My brother Jimi was at home in the studio. Valleys of Neptune offers deep insight into his mastery of the recording process and demonstrates the fact that he was as unparalleled a recording innovator as he was a guitarist. His brilliance shines through on every one of these precious tracks.'"
I don't doubt that she's absolutely right, but...
Janie was a young child when her mother married Al Hendrix, Jimi's father, in 1966. Jimi was already an adult and a world-famous phenomenon at the time. So when she goes on about "my brother Jimi", well... I take it with a grain of salt. The more accurate term would be stepbrother.
She's one of the luckiest people on Earth, to have been inserted into the Hendrix legacy like that. And she's making the most of it. For the details of Jimi's life and hideously tangled legal aftermath, and Janie's rise to control the estate, get an excellent book called Jimi Hendrix: The Man, The Magic, The Truth, by Sharon Lawrence.
