By all indications, Slash and Axl Rose are enjoying a harmonious second act as they play Guns N' Roses shows on an extensive tour billed as "Not in this Lifetime."

But guitarist Slash expresses misgivings about past GNR performances in the fourth episode of "Dave's Old Interview Tapes," a podcast that revisits IndyStar musical conversations between 1998 and 2004.

Without naming Indiana native Rose by name, Slash talks about a 1992 concert in Montreal in which 2,000 fans vandalized Olympic Stadium and looted a souvenir shop.

On the night Metallica cut its performance short because James Hetfield was hurt in a pyrotechnics accident, headliners Guns N' Roses were asked to go on a few minutes early to appease the crowd.

Instead, the band played later than originally scheduled. Rose, complaining of throat problems, lasted just 15 minutes onstage.

"There's definitely somebody responsible for that, but I'm not going to get into it," Slash said. "Really, one of the only regrets I have is any time fans have ever been disappointed. ... The thing that's irritating about it is that it's so (expletive) easy to go up there and do what it is that you do."

Slash talked to IndyStar in 2000, when his Slash's Snakepit band was on tour as the supporting act for AC/DC. In addition to audio from that chat, the podcast episode features commentary by Jake Query — co-host of "Query & Schultz" weekdays on Fox Sports 97.5.

On "Dave's Old Interview Tapes," Query talks about the lasting impression of a 1991 Guns N' Roses show at Deer Creek Music Center and he credits Slash for building lifelong relationships with bass player Duff McKagan and Los Angeles deli owner Marc Canter.

Elsewhere in the episode, Slash describes his drive to master a "raw, pure rock" sound and he shares the best career advice he ever received.

The eight-episode first season of "Dave's Interview Tapes" includes episodes devoted to Foo Fighters leader Dave Grohl, blues icon B.B. King and Dead & Company members John Mayer and Mickey Hart.
