Rockers Aerosmith have cancelled a concert in Sydney, Australia to co-headline a music festival with Van Halen.

The Walk This Way hitmakers were due to perform a solo show at the city's ANZ Stadium on 28 April (13), but they will now appear at the venue a week earlier (20Apr13) during the Stone Music Festival.

Tickets for the original gig will be valid for the re-scheduled show.

A statement from the band reads, "It is with great pleasure that we announce that Aerosmith will now be co-headlining the Stone Music Festival on Saturday 20 April, 2013 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, 2013 will no longer take place with all ticket holders receiving equivalent ticket allocation for the Stone Music Festival on Saturday 20 April, 2013."
