Ghana’s fastest rapper and Black Entertainment Television (BET) Best International Act award winner, according to reports, will headline a mega concert next month. The concert, dubbed You Know What Time It Is, sources say, will be staged on November 10 at the University of Ghana and will be a prelude to another concert scheduled to come off at the Dome of the Conference Centre on December 25. The two-time Ghana Music Awards Artiste of the Year winner will perform two exclusive songs from his new album, to be launched at the December 25 concert, at the Legon event. A top Nigerian musician, according to a source, might join Sarkodie at the November 10 concert. Widely known for his iconic “You know what time it is” signature, Sarkodie became the first Ghanaian to win BET Award in August this year. After featuring on this year’s BET Hiphop Awards Cypher and also winning the Best International Act at the Headies Awards in Nigeria, Sarkodie is hoping to bag the Most Gifted West African Video with his Saa Okodie No at 2012 Channel O Awards. This year's awards comes off at Walter Sisulu Square in Kliptown in Soweto, Johannesburg, South Africa on November 17.
