According to stubbadub.com the Melvins gig in Sydney will be held at the Annandale on the 22nd of January:

Almost 25 years, over 25 albums and still counting, the Melvins are considered one of the godfathers of sludge metal whom heavily influenced the Seattle grunge scene back in the 90’s. With a cult following across the globe, and including original members King Buzzo (Guitar/vocals) and Dale Crover (Drums/vocals), the band has recently released ANOTHER studio album, ‘Nude With Boots’.

And in the news that their Australian fans have been waiting for, this new release has inspired the boys to hit the road again! So on Thursday 22nd January, in a VERY special, VERY intimate show at Sydney’s Annandale Hotel – get ready to experience the Melvins performing their classic album ‘HOUDINI’ – in its entirety!! This will be their ONLY Sydney show, and with a line-up of the one ‘n only Buzz Osborne, Dale Crover & Trevor Dunn (Mr Bungle) on bass…Oh my goddddd!! www.myspace.com/themelvins

Word is that Mike Patton will be a special guest at the shows too.  Thanks to Adrian for the tip!
