An extraordinary video has emerged from Adelaide, Australia which appears to show US rapper Xzibit attacking a concert promoter.

Promoter Patrick Whyntie - who also raps under the name Mastacraft - promoted Xzibit’s Australian tour and played the support set on Wednesday night.

According to his Facebook post, Whyntie claims he left the stage to find Xzibit’s manager arguing and “disrespecting every staff backstage".

Whyntie claims he stepped in only to have Xzibit hit him with “some weird ass punch slap” and throw a chair at him.

Victor Lopez – the DJ for Australian rapper Kerser – explained on Facebook why Xzibit may have been aso angry.

Lopez claims the Pimp My Ride host was picked up from Adelaide airport in “a dodgy old Subaru with broken windows” and was forced to catch a taxi to sound check only to find that nothing had been set up.

Xzibit will continue his tour in Australia.
