Observations: One to watch - K. Koke, rapper, 27

K. Koke is being hailed by Jay-Z

"My story relates to a lot of people's stories, my experience relates to a lot of people's experiences," says K. Koke – which is quite a contention, considering he's been acquitted of attempted murder.

Still, that experience is far behind him now he's being hailed by the likes of Jay–Z, who has signed him as the first British rapper to his Roc Nation label. The north-west Londoner doesn't have an official single out yet, but he'll perform at Wireless Festival on Sunday.
