Give me a twelve bar shuffle in A, and I'll get my mojo 'a workin!
Oh yeah, I've done the music scene...and still have a gig every now and then. Of course, just as Glenski has pointed out, the wave that one may, or then again may never, catch a ride on will eventually hit the beach--and usually much sooner than you'd like it to.
I never shot for the professional scene, but did do a number of public scenes, and still get asked by some of the old local boys (who, by the way were once pro) to do a stage for some of the local festivals. The guy I had 'worked' with had made every effort to go pro...and his insistance on that is the main reason for our break-up back in '98. Needless to say, he never made it past that first CD which just didn't catch on.
I will never forget that one good Celtic group, Hardwood whose singer had even backed up Sting. Boy did they put down some foot stompin' numbers. They had approached me because I had been doing a radio show at that time, and I did pass on some demos, but...nope...the Celtic scene was not ready to be supported by the public's 'yen vote.'
There is a big Blues Festival each year in Tokyo, and some big names come. I have seen a few of the die-hard blues artists come here to Matsumoto for some small restaurant gigs...usually not big money.
To make a living here in Japan in the music scene, I'd say that you'd have to be a studio musician, you'd have to know Japanese pretty well, and of course, be very good on that instrument you play.
