Aerosmith have reportedly canceled their planned concert at the ANZ Stadium in Sydney, Aus to take part in the music festival. The local ticketing agency Ticketek Australia no longer lists the April 28th Sydney date, but the band still has it listed on their website. The festival appearance has been confirmed and announced by organizers.

Noise11 reports that Ticketek informed fans that purchased tickets for the ANZ date, "We are writing to you today to advise you of a major announcement pertaining to the tickets that you purchased for the Aerosmith concert scheduled for Sunday 28 April, 2013".

But they did have good news for those fans, "It is with great pleasure that we announce that Aerosmith will now be co-headlining the Stone Music Festival on Saturday 20 April - with Van Halen.

"Stone Festival will be Aerosmith's only Sydney performance and Van Halen's only Australian performance. Both bands will perform full, greatest hits sets.

"This will mean the original Aerosmith concert date on Sunday 28 April - will no longer take place with all ticket holders receiving equivalent ticket allocation for the Stone Music Festival on Saturday 20 April, 2013".

The two day music festival will take place in Sydney on April 20th and 21st with the first night featuring the aforementioned Van Halen and Aerosmith as well as Jimmy Barnes, The Living End, Noiseworks, Kings of Chaos, The Superjesus, Richie Ramone, Ian Moss, Choirboys, The Art, My So Called Life, Atlantis Awaits.
