According to a report on MyGNRForum, Caram Costanzo worked on Axl Rose’s new Looney Tunes song “Rock the Rock”. Costanzo was an assistant engineer on Stone Temple Pilots’ Purple, Stone Temple Pilots’ Tiny Music…Songs From The Vatican Gift Shop, Pearl Jam’s No Code, and Rage Against The Machine’s Evil Empire. He also co-produced Guns N’ Roses’ Chinese Democracy, and the unreleased material from that era that could compromise part of GNR’s reunion album with Slash and Duff McKagan. Rose working with Costanzo on this song, if the report is true, hints that Costanzo could definitely play a role on the next Guns N’ Roses album.
Axl Rose worked with several producers on Chinese Democracy for well over a decade, including Moby, Sean Beavan, and Roy Thomas Baker.
Former Guns N’ Roses and Nine Inch Nails drummer Chris Vrenna discussed Moby’s time working with the band in 1997 in a new AL interview.
“When I was there, Moby was going to produce. Axl didn’t come in very often; he’d show up about once a week. So sometimes we jammed. Sometimes me and Moby just sat and drank coffee and talked about music. Moby was rad.
“Can you imagine a Guns N’ Roses record with [guitarist] Robin Finck and me and Moby producing? And Axl really wanted it to have an electronic element. He kept referencing the Passengers album that U2 did [‘Original Soundtracks 1,’ a 1995 collaborative effort of U2 and Brian Eno released under the pseudonym of Passengers] – ‘It’s wonderful. It’s so good.’ That and Nine Inch Nails.”
