Huh, I posted this in a new thread because I just couldn't find it in the search.
To me this interview was a fascinating insight into how MM thinks. Not in the sense that he is happy or unhappy - he doesn't really go on that scale, or rather he could be on either point of that scale and still talk the way he does and we wouldn't know it. Mike goes from tortured to ecstatic, rather, and I think playing in a band both tortures and sparks his creative drive on very deep levels mentally.
Just look at how he talks about sound design. Putting a guitar over drums is already changing it. Recording the drums changes the sound, so you have to change it furthermore in post. To the way you heard it from a specific position, because it's different being behind the drums and in front of them listening! A kit brings a change, but you have to be able to be you on every kit. You have to be able to follow the music, but you can't have an 88-piece set. You have to adjust yourself to sound engineers and your band leader, except you want to be you, but you also want to serve the music. He is chasing an ideal sound of his instrument within a band, both live and in studio and in his head, that literally can't exist due to so many factors, and he is thrilled by the chase. This fascinates me.
He has gone through a similar journey with his relationship to fans. From being in a classroom where a small number of people judges him based on a few metrics, to the absolute chaos of hundreds of thousands of people judging you on very vague emotional grounds and sound aesthetics. I think he is starting to realize that he can only please himself (and that's if he can - go to the upper paragraph again). I feel like the only dangerous thing he is doing here is trying to explain himself, and let people know that the comments do hurt him, because people are trolls and will keep trolling him the more he protests. And trying to educate the crowd about what goes into a drum sound only goes so far, because the average reader will just say "I can't see why can't JP read that and give the drums more punch, then".
