"He is a great financial mind for the market. He plays that like I play guitar. As long as there"s a smile on Rupert"s face, I"m cool."-Keith Richards on Prince Rupert Lowenstein??In 1968 Mick Jagger couldn"t understand why the Rolling Stones were broke. The man he asked for help was a German prince, a merchant banker. They forged an unlikely alliance which re-invented the business of rock "n" roll. As a youthquake shook the Establishment, Prince Rupert Loewenstein thrived in both worlds, never relinquishing his elegance or decorum. For nearly forty years Prince Rupert worked with the Stones as-in his own words-"a combination of bank manager, psychiatrist, and nanny," usually enthralled with his clients but often bemused and exasperated with them, too. Coolly impartial and dryly humorous, this is a refreshingly different take on the rock "n" roll world from within its inner sanctum.
