Love this from Lefsetz ...
Not that I speak with Joni all the time. But I've had a few interactions. Not that she's crazy, but I will say she's difficult. Then again, she made the best self-confessional music of all time. Furthermore, she can play and sing and write. Do you think a normal person can do this?
OF COURSE NOT!
A normal person plays it close to the vest, is manipulative, whereas an artist is out there completely, warts and all. Artists need representation because they can't fathom the manipulation of business, they need protection.
