AC DC fans hoping to see Phil Rudd back behind the drum kit for the band's Grammy Awards performance next month (Feb15) will be out of luck because he has court date just two days later.

The drummer is not expected to make the trip to the 57th annual Grammy Awards in Los Angeles, because he'll be preparing for a case review hearing in Tauranga, New Zealand on 10 February (15).

Rudd is currently out on bail after pleading not guilty to both threatening to kill and drug possession charges.

The rocker was arrested in November (14), but maintained his innocence and insisted he fully intended to remain a member of Ac Dc, stating, "This has just been a big ball of cheese and all the rats are gathering and having a piece. That's just life, but that's not who I am. I want my job back, I want my reputation back, and I'm gonna get it back.

"I'm going back to work with Ac Dc. I don't care who likes it or who doesn't. Everyone listens to the wrong people. They should listen to me. I'm a good guy, and I'm a pretty good drummer, by the way."

A murder-for-hire charge against Rudd was dropped last year (14), with the man at the centre of the drama revealing the drummer attempted to hire him as a bodyguard, not an assassin.

The band has not indicated whether Rudd will be a part of Ac Dc's upcoming world tour.
