Seems like the sons of famous musicians can find initial success, but usually it's short lived. Julian Lennon put out two albums which sounded like a carbon copy of his dad, at a time when the whole world was still mourning John's assassination. Then on his third record, he quit trying to sing like his dad and instead tried to sound like 80's era David Bowie, and we didn't hear much from Julian after that.
Jakob Dylan had a big hit with his band the Wallflowers. Ironically it sounded more like Bruce Springsteen than Bob Dylan. I think the Wallflowers are still touring, but they haven't had any other hits that I'm aware of.
Hank Williams Jr actually found success by refusing to copy his father... and then lost it by being a racist douchebag, but that could have happened to any racist douchebag (and should!)
Lisa Marie Presley had a brief recording career, but it didn't really get her anywhere so then she went into the Scientology cult and gave a big chunk of The King's money to Evil Lord Xenu & his pal Davy the Cabbage (or whatever that fucking idiot's name is)
So the odds aren't really in Wolf's favor for lasting success. Maybe that's why he's taken a Tom Scholz/Axl Rose period of time to put out this damned record? I'll certainly give it a fair listen when it comes out... but I'll probably download a pirate copy first. Not gonna buy it if it sucks.
