Former AC/DC drummer Phil Rudd was wearing a jacket with the band's name on it when he left court today.
Rudd was arrested over the weekend and today was charged with a breach of his home detention conditions.
He is accused of possessing or consuming alcohol on Saturday.
Rudd did not enter a plea to the charge, with lawyer Craig Tuck saying one was likely at his next appearance on August 3.
The maximum penalty for the charge is one year in jail or a $2000 fine.
The Crown was granted a request that Rudd must provide samples whenever asked by Corrections.
The 61-year-old was last week sentenced to eight months' home detention on threatening to kill and drugs charges.
Judge Thomas Ingram told Rudd at the time that there "was nowhere to hide" and he would be jailed if he was found to have any traces of drugs or alcohol in his system.
Mr Tuck said the alleged breach will not jeopardise his appeal of conviction and sentencing.
Today's hearing last three minutes and Rudd was remanded on bail. As he left court, he told an associate 'gimme the key' before driving off in a Jaguar.
