Geffen is best known for controversial lyrics and behaviour. His songs voice a challenge to traditional values and address themes popular among youth - such as love, violence, drugs and alcohol, and parent-child relationships. His exotic appearance, ranging from his bizarre clothing to his heavy makeup, is reminiscent of David Bowie. Geffen was also one of the last artists to perform at the November 4,1995 peace rally in Tel Aviv at which Yitzhak Rabin was assassinated, and as such, one of the last to come in direct contact with Rabin. He also happens to be the nephew of former Israeli Foreign Minister Moshe Dayan.
