SLAYER CANCEL ADELAIDE SHOW DUE TO ILLNESS / MEGADETH TO PERFORM FULL SET

We regret to announce that Slayer vocalist Tom Araya was advised by his doctors not to perform at tonight’s show at the Thebarton Theatre in Adelaide due to severe laryngitis. Tom, his band and crew were on route to Adelaide with the full intention of performing but were forced to cancel the date due to doctor-mandated rest.

Co-headliners Megadeth have confirmed that they will perform an extended set at the Thebarton tonight. This continues a run of jaw dropping shows for Megadeth in Australia – amongst the finest that Dave Mustaine and Co have delivered on these shores.

The remainder of the shows will proceed as planned, with Slayer and Megadeth performing at Challenge Stadium in Perth this Tuesday 13th October, and Slayer performing a full set including the classic Reign in Blood album in its entirety at Luna Park Sydney this Thursday 15th October.

Slayer extends an apology to their Adelaide fans for their cancellation, and ticket holders who no longer wish to attend can obtain a refund from point of purchase.

Dave Mustaine sent an invitation to Slayer to have Kerry King join Megadeth on stage because of this unfortunate situation, and we are still awaiting his reply.

Ticket holders who no longer wish to attend can obtain a refund from point of purchase.
