Details have been announced for Slayer guitarist Jeff Hanneman's memorial celebration.

Hanneman passed away on May 2nd at the age of 49.

It has been learned that Slayer guitarist Jeff Hanneman's cause of death was alcohol related cirrhosis.

Today the band released a statement remembering some good times they shared with Hanneman.

Kerry King: "I had so many great times with Jeff...in the early days when we were out on the road, he and I were the night owls, we would stay up all night on the bus, just hanging out, talking, watching movies...World War II movies, horror movies, we watched Full Metal Jacket so many times, we could practically recite all of the dialogue."

Tom Araya: "When we first formed Slayer, we used to rehearse all the time, religiously, 24/7. Jeff and I spent a lot of time hanging out together, he lived in my father's garage which was also our rehearsal space. When he got his own apartment, he had an 8-track and I would go there to record songs I'd written, not Slayer songs, other stuff I'd written. At a certain point, you still have the band but you start your own lives outside of the band, so that 24/7 falls to the side, you don't spend as much time together as you once did. I miss those early days."

Kerry King: "He was a gigantic World War II buff, his father served in that war, so when Slayer played Russia for the first time - I think it was 1998 - Jeff and I went to one of Moscow's military museums. I'll never forget him walking around that place, looking at all of the tanks, weapons and other exhibits. He was like a kid on Christmas morning. But that was Jeff's thing, he knew so much about WW II history, he could have taught it in school."

Tom Araya: "We were in New York recording South of Heaven. Jeff and I were at the hotel and we had to get to the studio - I think it was called Chung King, a real rundown place. So we left the hotel and decided to walk, but then it started raining. We walked maybe five blocks, and it was raining so hard, we were totally soaked, so we decided to get a cab. Here we are, two dudes with long hair and leather jackets, absolutely soaked, thumbing to the studio. No one would stop. We had to walk the entire way."

Tom Araya: "Jeff was a lifeline of Slayer, he wrote so many of the songs that the band will always be known for. He had a good heart, he was a good guy."

Slayer guitarist Jeff Hanneman has died.

"Slayer is devastated to inform that their bandmate and brother, Jeff Hanneman, passed away..." the band said in a statement.

Hanneman contracted necrotizing fasciitis, a rare skin infection also known as flesh-eating disease, in 2011, and hadn't been touring since.

It's not know if the disease played part in his liver failure.

Hanneman was 49.

Slayer have issued a statement regarding their decision to replace drummer Dave Lombardo on their upcoming Australian tour.

"Last year, I discovered 90% of Slayer’s tour income was being deducted as expenses including the professional fees paid to management, costing the band millions of dollars and leaving 10% or less to split amongst the four of us," Lombardo said. "In my opinion, this is not the way a band’s business should operate. I tried rectifying it by letting my band mates know, and Tom and I hired auditors to figure out what happened, but I was denied access to detailed information and the necessary back up documents."

Today Slayer issued their own statement.

"Slayer confirms that Jon Dette will drum for the band on its Australian tour that starts this Saturday, February 23 in Brisbane," the statement said. "As regards Dave Lombardo‘s Facebook post, Slayer does not agree with Mr. Lombardo‘s substance or the timeline of the events, except to acknowledge that Mr. Lombardo came to the band less than a week before their scheduled departure for Australia to present an entirely new set of terms for his engagement that were contrary to those that had been previously agreed upon."

"The band was unable to reach an agreement on these new demands in the short amount of time available prior to leaving for Australia. There is more to the account than what Mr. Lombardo has offered, but out of respect to him, Slayer will not be commenting further. Slayer is grateful to its Australian fans for their understanding of this unfortunate last-minute change, and very much looks forward to seeing them at these shows."

Slayer have plans to put out a four-song EP prior to the release of their next album, drummer Dave Lombardo told TheNervousBreakdown.com.

The band currently has nine new songs written.

Philm, featuring Dave Lombardo (Slayer), Pancho Tomaselli (War), Gerry Nestler (Civil Defiance), have signed with Ipecac Recordings.

The band's debut album Harmonic will be released on May 15th.
