A lot of what happened in Detroit is the result of what happened to Americas manufacturing industry and the flow on to the live music scene as the city died...............

I was particulary thinking of live music venues as the engine room of a vibrant music scene and the flow on, creating the need for an equally vibrant recording scene.
Yes, Metropolis, Platinum, RBX, Eatons, Fast Forward, Sing Sing....... I have recorded in all of these except Fast Forward and it's a bit of a travisty that Sing Sing is the only one left. I know Phil Butson who was a part owner of Sing Sing reasonably well. We used to live in a shared house and he and his wife played at my wedding. He's a great guitarist and engineer..... anyway, he went through quite a few years of dismay, at seeing what was gradualy hapening to the studio business before he decided to opt out of Sing Sing and scale down to a home based recording and production studio.
I think Melbourne's live scene is keeping a healthy plethora of small studios with low overheads doing great work around particular "frienship /music networks" , and an ever growing plethora doing not so great work, but it is rarely a profesional level income.
I just hope Melbourn's live music scene stays as vibrant as it is and even expands, as I don't think Melbourne will go the way of Detriot as a city.....if it does, .... see ya later........ I'm off in my boat!
