What makes a good band
A band who doesn't listen to the advice of SOFTies
(Slaps own forehead with a fish and a kangaroo!)
A band who does their own shit and paves their own way
A band who detaches themselves from the local scene and focuses on winning over the bigger market of their choice, the 99.9 percent that doesn't care about local scene politicking or patting the backs and stroking the egos of cynical, over-the-hill duds.
A lot of local bands make the mistake of becoming TOO involved in the local scene - worrying what others think, worrying about politics, worrying about how they compare to other local bands - the best way is to don't give a flying lovelovelovelove about petty rivalry and focusing on making a name for yourselves.
The smartest thing you can ever do is to never consider yourself part of a clique. To be your own individuals. Indie scene cliques pride themselves in the collective, but at the end of the day, if you're playing to the same 50 people, then I don't see the point in whether you're 'good' at not. I do not constitute playing to 10,000 people at Baybeats and selling 50 albums afterwards to be something you're shooting for as well.
Fact: If you're a good band, loads of local scene people will heap loads of praises on your shoulders
Also A Fact: At the end of the day, most of these people don't buy your albums anyway.
But
that definition of good is measured in proportion to success (be it off-beat or mainstream). You can still be a good band either way - just that you'll be good in the eyes of maybe just your friends and yourselves. But given that you posted this question in a public forum, I don't think that's what you're aiming for.
So if your definition of 'good' means a band that has a large number of people who appreciates them, the wisest thing to do is pull yourself away from the local scene as far as you can. You will get a lot of backlash - people will call you betrayals, people will call you sellouts, people will call you whatever the hell they want. At the end of the day, if you get more fans, sell more CDs, go further in your career, you will be the ones laughing your way to success while the 50 or so cynics continue to complain about how life is unfair and worry about whether others think they're 'good' or not.
Then you can scroll back up to the very first point I made
and not listen to the advice of SOFTies
