Rapper Kanye West has refused to let news of his album leak halt his plans to promote the record by moving forward with his ambitious scheme to project his music videos at locations all over the world. The hip-hop star debuted the promo for New Slaves, from his upcoming album Yeezus, last month (May13) by projecting the clip onto several buildings across the world. West was dealt a setback on Friday (14Jun13) when tracks from the unreleased album began appearing on file-sharing websites, but he refused to let it halt his promotion plans. The star debuted more new songs on Friday at various locations, including cities in his native U.S. as well as London, Paris in France, Amsterdam, Netherlands, Sydney in Australia and Johannesburg, South Africa. Yeezus is officially released next week (begs17Jun13).
