Goldie Lookin' Chain have been added to the bill at the tsunami benefit gig at Cardiff's Millennium Stadium.
The group will join the Manic Street Preachers, Stereophonics' frontman Kelly Jones, Eric Clapton, Snow Patrol, Feeder, Keane, Embrace and Badly Drawn Boy reports NME.com.
A statement from the band said: "It's all about the people who've gone out and bought these 60,000 tickets in record time, we're just doing what we can to help."
Organisers are hoping to raise £1 million for victims of the disaster from the show, which will kick off at 3.30pm on Saturday.
