A feud between AC/DC and Axl Rose could blow up if the band continues playing with the Guns N’ Roses frontman.

Former AC/DC drummer Phil Rudd has stressed that he will not rejoin his bandmates if the band will not drop Rose. Although he has yet to be invited to return, Rudd already made a condition for his comeback – there should be no Axl Rose with AC/DC.

Rudd was kicked out of the Aussie rock band after his drug possession and murder threat conviction in 2015. He was sentenced to eight months of home detention. Chris Slade has been filling in for Rudd’s role. Rose, on the other hand, has been fronting AC/DC since Brian Johnson was forced to step aside due to a hearing problem.

“If Angus (Young) wants me to play, then that’s up to him – but I don’t really want to play with Axl Rose. I don’t really rate him,” Rudd told NZ Herald.  Rudd said he would not rule out a return to AC/DC. He, however, added that he is focusing on his own music for now.

Rudd also revealed that he had just recovered from a heart attack.

The future of AC/DC is still unclear. Frontman Angus Young recently admitted that he is unsure of the band’s future once their tour concludes this month. By then, Young will become the last man left from the original members of AC/DC. Bassist Cliff Williams recently announced that he will retire after their current tour.

AC/DC is set to perform at New York’s Madison Square Garden on September 14.

Meanwhile, Guns N’ Roses ended their Not In This Lifetime US tour late last month. The band is scheduled to kick off their Latin America tour on October 27.

Axl Rose and the rest of GNR also recently announced their tour in Australia and New Zealand.  The Not In This Lifetime tour in Australia is set in February 2017.
