I used the band index thread to find the QR thread, and this is the one that came up. Seems old, but I couldn't find the newer thread using the search function for some reason. Anyway, Ray Alder from Fates Warning recently commented on QR's Brazil Incident:
Link: https://www.bravewords.com/news/211107BraveWords: Before, you mentioned the tour Fates Warning did with Queensr˙che and Dream Theater. Could you see trouble brewing between Geoff Tate and the other members of Queensr˙che?
Ray Alder: "I didn't really see it coming; we played with them in Sao Paulo, when the whole thing went down. It was crazy, it was really insane. I mean, literally, there was security on stage and the promoters were freaking out. And everything went on that night and then the band left. I was hanging out with Geoff later, and we went to a bar. It was just the funniest thing - Geoff and I sat there…and talked about scotch. We didn't talk about what the hell just happened! It was the weirdest thing, I don't know why it came up. But no, I did not see that coming. But I think Queensr˙che is Queensr˙che - it's not Geoff Tate. Unfortunately, it just didn't work out, and they went their own ways. I like the new Queensr˙che album."
