Aerosmith have canceled next Saturday's concerts in the Indonesian capital of in Jakarta "due to safety reasons" following an alleged bomb plot, according to Billboard.

The band were scheduled to perform at the JIExpo on May 11th as part of their Global Warming World Tour, but the promoter announced that they have canceled the nearly sold-out show.

The promoter's website ran announcement from Aerosmith's reps that read, "Unfortunately, we have to cancel our upcoming show in Jakarta. We want to apologize to all our fans who were expecting to see us and hope that one day we can make it up to them."

While the band's announcement didn't mention the safety concern in their statement, Billboard reports that that the security concerns may have come from an alleged bomb plot that was targeting the Myanmar Embassy.

Helmi Sugara, a spokesman for the event's organizer, said that the band canceled the show on Saturday. That followed Friday's announcement by Indonesia that they had arrested two suspected militants with bombs.

They report that it was not clear if the show cancelation was directly related to the terror plot or if it was a reaction to some other threat.

Slayer have confirmed that guitarist Jeff Hanneman died yesterday at the age of 49. He suffered liver failure while in a hospital near his California home.

He'd been struggling with health issues since a near-fatal spider bite in 2011, which had kept him sidelined ever since. The official statement says:

"Slayer is devastated to inform that their bandmate and brother, Jeff Hanneman, passed away at about 11am this morning. He was in an area hospital.

"He is survived by his wife Kathy, his sister Kathy and his brothers Michael and Larry, and will be sorely missed. May he rest in peace."

Hanneman co-founded the band with fellow guitarist Kerry King in 1981 and alongside frontman Tom Araya and drummer Dave Lombardo they rose to become one of the Big 4 of thrash metal following their 1986 breakthrough album “Rein In Blood.”

Former Guns N' Roses drummer Steven Adler has returned to rehab, forcing his band solo band Adler to postpone their summer touring plans until the fall.

Adler singer Jacob Bunton has released a statement saying: "We are truly sorry to all of the fans and promoters who were looking forward to seeing us on the road, but right now Steven's health is the most important thing. We hope to make it up to everyone when Steven recovers."

The drummer has been fighting addiction issues since the 1980s and booted from GNR in 1990 due to his inability to control his drinking and drug-taking.

In January he said the release of new album “Back From The Dead”, and the positive reviews for Adler's live shows, meant his drug problems were behind him.
