I have in my mind an image of the stereotypical high school or college band: full of dreams but lacking in skill or originality. And frankly I don't want to end-up like that.
So basically I have two questions regarding this:
1) Why does this happen with these bands? What is the common denominator that these "typical high school bands" have that makes them so unstellar?
Immature people often get bigger-than-deserved egos. Any minor success, such as getting 12-15 friends to tell them that they're "awesome, dude!" just feeds that & makes it worse.
Another issue is that the ability to really listen to music is a skill that most people need to work at & develop. Many younger players tend to isolate one instrument in their minds (usually their favorite) & think that as long as that one riff is "nailed" all is great. They completely miss the critical interrelationships of instruments needed to produce a good, overall
band experience.
2) How does one avoid this problem?
Short answer: Grow up! (easier said than done!)
First, lose the "I know what's 'good'" attitude. I'm not trying to imply that you (OP) or anyone in particular has that attitude, but a lot of "kids" (I was one once, for way too long; I know at least a little about what it's like) think they know everything (and/or will live forever, are bulletproof, etc.). That's understandable, considering that anybody in their late teens to early 20s especially has just gone through a major life-phase-shift & really
has learned a heck of a lot in a pretty short period of time. What they may not realize, though, is that it's (the learning process) a long way from being over.
You may be "good", or even "great", at playing your instrument. You may have the greatest taste in music & "know" more about what's "good" & not than anybody else in the world. None of that matters if you have any interest at all in appealing to more than just yourself. The only opinions that matter are those of the audience, and you have to truly care about
them if you want them to care about you.
Simple formula:
1. It's not about you (the musicians)
2. It's not
even about the music
3. It's all about
them; the audience/listeners
Some people figure this out a young age, while others never get it in their whole lives. I just jammed last week with a 50-something guitar player who couldn't seem to shut up about how awful just about every other local musician is (when he wasn't droning on about his
own awesome talent & skill, dropping big names that he knows, etc.). The guy was an OK player, but certainly nowhere near "God's gift to the guitar" like he seemed to believe.
I think that the smartest thing a young person can do is to figure out exactly what they want to do, then work up a plan to make that happen. I really admire those who, at a young age, figured out what they wanted their lives to be & got it done - even if "all" they wanted was a good job, family, fishing on weekends, comfortable retirement, etc.
