(AllHipHop News) Hip-Hop took over the stage this year at Wireless; a three-day festival which took place at the Queen Elizabeth Olympic Park in London from July 12-14 2013. This year, the festival’s main headlining acts were Snoop Lion, Nas, A$AP Rocky, Kendrick Lemar, John Legend, Will.I.Am and many others. Jay-Z and Justin Timberlake capped off the Festival on Sunday (14 July) by giving the audience a taste of Legends of Summer tour, which is due to kick-start in North America on July 17 in Toronto. The duo was also joined by Rihanna, who appeared as a surprise guest, for a rendition of the track Run This Town. The other main headliners of the festival were the legendary group, A Tribe Called Quest. During the group’s performance, Q-Tip made reference to the Trayvon Martin case by stating “This is not the first time it has happened where a young black man in our country, in America, life is devalued so grossly.” Q-Tip praised the system in the UK by admiring the way information is analyzed before making a verdict. He asked the crowd to pray for America and said “There’s a lot of motherf***ing black on black violence going on in Chicago and Miami and all over our country man. We are losing our youth at an incredible rate. We need you to pray for us man.” It was the first time in over 10 years, the group performed as a trio in the UK’s capital.
