Doug Goldstein, the former longtime manager of Guns N’ Roses, who saw the hard rock group through the heights of commercial success and chaotic periods of rock ‘n’ roll excess, has died. He was 65.

His death was announced by Brandon Weissler, host of the Guns N’ Roses-focused podcast Appetite for Distortion. Weissler had worked with Goldstein some years back on the manager’s since-abandoned memoir.

“Many of you know that a few years ago, Doug and I were working on his autobiography together,” Weissler writes on Faceback. “Once others tried to get their hands on the project, it didn’t end well. At the time, I felt betrayed. I was wrong. What I used to think was a waste of time writing a book that never happened, I now cherish the hours of conversation with Doug.

“Doug was ALWAYS kind and supportive of me,” Weissler continues. “He made me feel good about myself, ALWAYS. I took a rejection from a publisher too hard, and it wasn’t Doug’s fault. We did reconcile, but our friendship was never sadly the same.”

Goldstein’s relationship with the band featuring singer Axl Rose and guitarist Slash began around the time the group was promoting its debut album, 1987’s Appetite for Destruction. Goldstein first worked as tour manager and, later, as co-manager with Alan Niven. In an account of the era, the magazine and website Ultimate Classic Rock writes: “Goldstein’s job was, by all accounts, a thankless one. He entered the GN’R orbit while the band was hard at work promoting Appetite for Destruction — first as a tour manager, and later as co-manager alongside Niven. Prior to Guns N’ Roses, he’d worked security for the likes of Van Halen, Heart, Black Sabbath and other acts, according to Mick Wall’s 2016 Guns N’ Roses biography Last of the Giants.

“Immediately,” the magazine’s account continues, “Goldstein was tasked not only with keeping Guns N’ Roses functioning on the road, but keeping the band members alive. Associates of the band credited him with being social and amenable — a so-called ‘good cop’ to Niven’s hard-nosed, business-oriented ‘bad cop.’ But Goldstein could drop the hammer when needed. In Last of the Giants, he recalled an early anecdote involving Slash that helped him curb the band’s own appetite for destruction, at least partially.”

“Finally Slash breaks a [hotel] TV,” Goldstein recalled in the book. “So he calls me.” Goldstein approached the hotel’s reception desk to discuss the matter. “The guys say okay, and that the set cost $350. I go, ‘No way.’ And Slash is waiting for me to bring it down, right? I go, ‘Not a chance. That is not a $350 TV. That’s a $700 TV.’ Slash is like, ‘What?’ I go, ‘Slash, shut up. I do this for a living and I know a $700 TV when I see one.’ The guy is like, ‘No, really. Just give me $350.’ I go, ‘Shut up! I do this for a living.’ I go, ‘Slash, I’m gonna have to take $700 out of your money.’ So now it’s not even a band deal, I’m taking it out of his personal income. He was f*cking livid! But I’ll tell you what. Nobody broke shit after that.”

Goldstein, Weissler told Ultimate Classic Rock, “was a friendly ear, a supportive voice and a sensitive man. You don’t survive 17 years with Axl Rose by accident. In many ways, he saved Axl’s life.”

Last of the Giants details Goldstein’s presence at the infamous 1991 St. Louis concert riot and other “near-disasters” throughout the 1991 Use Your Illusion tour, including the increase substance abuse of Slash and bassist Duff McKagan.

“Whenever I talk about it, I allude to the bunker mentality in wartime,” Goldstein is quoted as saying in the book. “You know, three guys in a bunker and shots are being fired over their heads and they’re bunkered down for a week at a time. By the end of that week there’s so much PTSD that takes place and you’ve gotten so much closer because of it.”

The hard-rocking Appetite for Destruction was a stone-cold smash, albeit an initially slow-burning one. Featuring such classic tracks as “Welcome to the Jungle,” “Paradise City” and the No. 1 pop single “Sweet Child o’ Mine,” the album topped the Billboard 200 in August 1988 — more than a year after its release. It has sold more than 18 million copies in the U.S. alone and is among the 20 top-selling LPs of all time.

The Los Angeles-based group followed it up with the slapped-together G N’ R Lies in 1988 before releasing a pair of studio albums — Use Your Illusion I and Use Your Illusion II on the same day in September 1991 and embarking on an extended world tour. The band’s next album, 1993’s The Spaghetti Incident?, would be its last for 15 years.

Along with many Appetite for Destruction cuts, the group’s best-known songs also include “November Rain,” “Civil War,” “Patience,” “You Could Be Mine” from the film Terminator 2: Judgment Day and covers of Wings’ “Live and Let Die” and Bob Dylan’s “Knockin’ on Heaven’s Door.”

Goldstein remained with the band through the late-’90s/early 2000s recording of the album Chinese Democracy, often weathering accusations of favoritism toward one band member or another. By the time that album was released in 2008, Goldstein had been retired from the music business for five years.

By 2012, Goldstein was living in Hawaii and working in real estate, contributing to a local website-blog under as “Your Rock-N-Roll Realtor.” In one blog entry, he wrote of attending the Freddie Mercury tribute concert at Wembley Stadium and meeting Elton John, Mick Jagger and Cat Stevens.

“I had quite a day,” Goldstein wrote, meeting Mick Jagger, seeing Cat Stevens, and watching my band play in front of 120,000 people. I loved my job and got to travel all over the world. Thank you to Axl Rose, Slash, Duff, and the rest of the members for allowing me the opportunity to handle your business affairs.”

Goldstein is survived by two sons, Jake and Eli. Information on other survivors was not immediately available.
