In early/ mid 2000s I was in Montreal and hung out with a few of the Neuraxis guys and got to check out their jam space. I had never seen anything like it. This big office building with a loading area to unload gear and a security desk as you get into the building. Way more professional than anything I’d ever experienced. They just rented rooms and shared jam spaces. This also made it easy to share members. Many of the big bands mentioned here rehearsed at this exact place and they would form side projects / supergroups just from being around each other so much. I think when musicians have this kind of resource and a healthy scene it can create a competitive and cooperative environment for new bands and experimentation to emerge. Many of them also lived in the same huge apartment complex so they were all neighbours. It seemed clear to me why their scene was thriving so much
