That too is correct, but it is a negative attitude. If a band wants to make it to the top, they have to be prepared to take risks on the way.......they HAVE to have a positive attitude at all times. That is on top of having ability, talent, drive, thick skin, etc,. etc.
The "model"/pipe dream you have quoted is still being touted as the way it should be done, BUT there are fewer and fewer venues prepared to take in relatively unknown "originals" bands, and fewer and fewer kids patronising gigs of this nature.
You and I recently communicated over an mp3 I posted. Your comments in general were quite positive. That band has approx 40 songs of similar (some better) quality, but guess what? That band finds it virtually impossible to get gigs in this city......because they sound too commercial.
