Rocker Tom Araya was suffering with vertigo and dehydration before he was hospitalised ahead of a Slayer concert in Sydney, Australia on Sunday (27Feb11), according to his wife.
The thrash metal stars were forced to axe their set at the touring Soundwave Festival at the last minute when Araya was admitted to a medical centre with an unknown illness.
His wife Sandra has now explained to fans Araya was exhausted.
In a post on Facebook.com, she writes, "(Tom) was suffering from vertigo due to extreme dehydration and lack of rest.
"Our doctor is in the process of getting the results on the test that were ran... Hopefully there will be nothing more to add after the results are returned."
Araya is expected to return to the stage alongside Iron Maiden, Slash and Queens of the Stone Age for a concert in Melbourne on Friday (04Mar11).
The video also features an appearance from model Tyson Beckford and ‘Empire’ star Jussie Smollett.
