A recent rumor floating around was that Guns N' Roses would be contributing new music to the new Terminator movie. The story stemmed from a fan page stating the following (much like Tool fans did for 13 years).
“A source who was working On Terminator dark fate has informed that 4 members of guns n roses went to a private viewing of a rough copy of the upcoming Arnold Schwarzenegger sequel movie to see if they want to put a song on the soundtrack. Apparently, Slash was at axls house to record overdubs on a song for the rush release. At this point the song name is unknown. But yes 100% verified. Guns n roses new music.”
Now in an interview with Trunk Nation, guitarist Slash says the rumors are just rumors and there's no actual substance to them.
"These rumors, they take off and then they get a life of their own. And you can't reel 'em in. They just sort of get tossed around in the wind. Anyway, but, yeah, so there's nothing in there, in that."
Later in the conversation, he does add that Guns N' Roses is definitely working on some new music. When that's coming, he doesn't say, but does mention that the band's focus is on touring right now.
"We're just doing this one run [of shows] in the States and a couple of dates in Mexico end of this month into November. And so that's it for Guns for now. And I think we have something coming up in March as far as touring is concerned. Obviously, everybody knows that we're working on new material, which is really exciting, and so, that's really primarily what the focus is."
