Muse have chosen to alter their Australian September schedule and arranged an all ages concert in Brisbane with a larger capacity. The the River Stage in the Botanical Gardens of Brisbane will host Muse on Sunday, 12th, September. Thanks to those that brought the age restriction to our attention. The date of the Adelaide show has now been moved to Tuesday, 7th, September. The gig in Adelaide will still be in Thebarton Theatre.
All ages then :)
Also, someone from the Muse.mu boards posted a review from NME, which can be found here
