You’re lucky, I encounter it a lot, whether online or in real life. Yeah, the perception you mentioned is way more common, but I still think it’s an unfair one. In many, many bands there’s one person who has the vision and is the architect of everything, and they’re celebrated for it rather than maligned. Given the quality of the output, especially on the initial run, I think it’s fair to say he didn’t make a mistake.
I personally wasn’t interested in it, but The Siddartha thing shouldn’t have been as controversial as it was. It’s not like people showed up to a Smashing Pumpkins concert and got that instead - it was just a small personal project done on his own time. Plenty of artists do stuff like this and don’t get torn apart in the press for it - they just get a “oh, they did something this weekend” blurb and that’s the end of it.
The long, reworked songs he does live definitely aren’t going to appeal to everyone, but I think they’re what make the shows special (even if sometimes they can be frustrating). It’s always been that way, even at the band’s peak - people would boo and curse him and walk out of the '97 Silverfucks, and now they’re widely regarded as the “holy shit, I wish I had been there to hear that” moments.
