Universal Music Australia has today announced that in conjunction with XBox, US supergroup Pussycat Dolls will perform a very special concert on the northern boardwalk of the Sydney Opera House. It’s the first in what’s expected to be an ongoing series of concerts put on by Microsoft’s gaming unit throughout Australia in support of their new game ‘Lips’ (Microsoft’s answer to the popular ‘Singstar’ from Sony). The ‘XBox Sounds’ concerts will take in most of the Australian summer, with dates planned between October this year and April 2009. The great news for fans is that tickets to the concerts are free! For more information, head to the XBox Sounds website at www.xbox.com.au. Curiously, there’s no mention of exactly WHEN the concert is to take place, but other Aussie fans can take great comfort in knowing that the official press release also reveals that a 2009 Pussycat Dolls Australian tour announcement is imminent.
