| Joey,
The studio scene is such a closed scene in any city these days that nothing will come from dropping off demos. Producers have a crew of people in place for what they need, and that comes from hanging out with the right people.
If you know JR Robinson, then you might end up on some sessions. But right now in LA there are the following guys, pretty much in this order working...
Neil Stubenhaus
Nathan East
Lee Sklar
Tim Landers
Jimmy Earl
and that will pretty much do it for LA I think. maybe there's a superstar that I'm forgetting, but that's about it right there. I live half in LA and half in NYC. I know all those guys, some better than others. and I know a ton of great musicians in LA too, and it doesnt' really make much difference. It's a click of people that have been working together since michael jackson was first making solo records with Quincey Jones, and they're still working together. It's just how it is.
Touring is really one of the only ways to make a living as a bass player these days, unless you become a producer and have a home studio.
You need to hook up with Barry Squires, and go on some auditions. That would probably be the best way to get into the scene there. There is also Ricky Minor who basically runs the live TV show scene, as well as being musical director for some of the biggest acts in the world. He's a bass player though too, so he does end up playing on a lot of the gigs he's fixing.
It's a tough one, and unfortunately I think a little bit of touring is the best way to break in.
Easy,
Janek |
