The Veronicas
I think/hope they'd do really well here actually.. and I'm really happy that their hard work in the US payed off.
I renember on the Veronicas Board a while ago.. because the UK/European fans were wondering why there's been no releases here and so on, Lisa replied to the topic saying that the head of WB America won't allow them to release their music anywhere else in the world until they crack the US market.
Since then I've heard that Untouched may be released here during the summer, woo!
