The Darkness, Dido and Busted have all been confirmed as performers at the Brit awards next month.
Dido will be making her first major TV performance of 2004, while Busted have promised fans a "very unusual performance", in what will be their first ever big award show.
Other performers at Earl's Court on February 17 include Muse, Black Eyed Peas, 50 Cent and Duran Duran, who are set to pick up an Outstanding Contribution to Music award.
A further two major live acts will be announced next week.
Meanwhile, Brit organisers have confirmed that Dido, who is favourite to win the Best British Female award at the Brits, will be eligible for an award, despite claiming she is Irish.
A spokesman for the Brits said: "Dido does claim to be Irish but because she has a British passport she will be eligible.
"But for people like U2, Westlife and Kylie, they have to go in the international category."
