Caught live Rìhanna

That sad,Rihanna isn't your everyday artist.For a start,she's been off duty for the best part of nine months nursing the fall-out from her vicious assault at the hands of ex-boyfriend Chris Brown.Secondly,she did what all decent comeback artists do best and thrashed out an adrenaline -fuelled,hit -crammed medley that forces fans to forget all about the nightmare that was 2009.Old favourites don't stop the music,Disturbia and Umbrella triggered the loudest response of the short -luved evening -albeit one that succesfully propelled Rihanna back to the forefront of contemporary music.But the most raucous cheers were reserved for surprise guest,her rap behemoth boss Jay-z,who demonstrated his masterful ability to get the crowd leaping of its toes for their storming rendition of Run This Town oddly Rihanna appeared most comfortable singing- and gyrating - along to new tracks Russian roullette :and hard at the Brixton academy gig.
