Headlining the Saturday main stage at this year's Sundown Festival will be popular rapper Dizzee Rascal.

Best known for his number-one hits Dance Wiv Me, Bonkers, Holiday, Dirtee Disco and Shout, he shot to fame after his debut solo album, Boy in da Corner, won him the 2003 Mercury Music Prize.

His follow-up albums have all reached gold status, after selling 100,000 copies, and his last, Tongue n' Cheek, went platinum after selling over 300,000.

He will be joined by Olly Murs, who found fame through the X-Factor, and Pixie Lott on the Saturday main-stage.

Murs, 27, finished as runner-up in the 2009 X-Factor but has gone on to have three number one singles and a number one album, far surpassing the winner of the 2009 X-Factor, Joe McElderry.

Pixie Lott has enjoyed an equally rapid rise to success, despite being just 22 years old, after her debut single Mama Do, went straight to number one in June 2009.

They are joined by the likes of Romanian dance success Alexandra Stan and female pop trio Stooshe on the Saturday main stage, before Dizzee Rascal brings the curtain down on the first day.

The line-up represents more of an emphasis on pop music, after last year's festival focused more on urban acts, such as Tinie Tempah, Taio Cruz, Tinchy Stryder and N-Dubz.

More acts are due to be added to the line-up this summer.
