The meteoric rise of David Geffen is told by Wall Street Journal reporter, Tom King. King's business background was invaluable in researching and explaining Geffen's deals... in some parts there is a different deal on every page.
Geffen seems to be living on adrenalin be it his hard charging in your face negotiating or his indulgence of artists and friends. He crashes hard too, finds therapies and cries when hurt or moved. To paraphrase one of his artists, it's like the sound of his own wheels drive him crazy.
When he bet on a star he went all the way, as he did with his first artist-Laura Nyro. He housed and fed them. Sometimes he provided lawyers for them and sometimes took them on trips. He gave his top managers wide decision making authority. Besides salaries they could be surprised by bonuses of cars or houses. Not knowing the industry norm, it's hard for me to judge if those who felt he didn't do enough them (after their/his success) have legitimate complaints.
Years, differences and feuds can separate him from family, friends, mentors and staff. There can be a kiss and make up (Cher, Spielburg, etc.), sometimes just separation (Nyro, Roberts, etc.) and sometimes a continuing freeze (Ovitz, Loddengaard etc.). He can be very generous, for instance giving Jackson Browne his copyrights or subsidizing cousins he doesn't know. He can also give to get, for instance rescuing his friend Calvin Klein paid him well at the end.
His success began with falsifying his resume, opening others' mail and forging mail. He intimidated, reneged, spread disinformation, brown nosed and bad mouthed. A lot of these very same tactics were used against him.
His talent was knowing entertainment that would sell, and he was usually right on the mark. His mistakes seemed to come when he worked with established stars, not the artists he "discovered".
This is an almost 600 page book, but you have the feel that there is much more to be written.
