The charges faced by AC/DC drummer Phil Rudd relate to an alleged threat to kill a man and his daughter, New Zealand prosecutors have said.
The details of the allegations have been made public for the first time, a day after Mr Rudd breached his bail by having contact with a witness.
Mr Rudd has denied threatening to kill and drug possession.
He was originally also charged with attempting to procure murder, but this was later dropped for lack of evidence.
New Zealand prosecutors on Friday released details of their allegations against him, stating that on the morning of 26 September, Mr Rudd had made two phone calls.
The first was to a business associate where he allegedly “spoke about what he wanted done to” the an unnamed man, who had been working for him for three years.
The second phone call was to the man himself, in which Mr Rudd allegedly “threatened to kill him and his daughter”.
