Jay-Z learnt to perform by observing Bono

London: American hip hop artist Jay-Z has confessed he used to be a "horrible" performer and had to study U2 singer Bono to learn onstage tactics. "I used to be a horrible performer. I was terrible, because I`m not really an animated guy and really move around, so I had to figure out a way how to convey my message and talk to people in compact movements, all the while, being entertaining," contactmusic.com quoted Jay-Z as saying. "There is a very thin line between not moving and being boring... He (Bono) doesn`t move around, he`s just a powerful performer. He knows how to exaggerate his movements. He knows how to have that conversation, without moving around much. I don`t know if he moves... anywhere. He`s a dynamic performer," added Jay-Z. IANS
