Quote Mike Stranks:
Well, yes, if you've got a band/group that's:
* of a very high standard musically and
* actually listens to the other members and
* knows enough sonically to know what to do to 'blend' and
* is willing to sacrifice "my sound" for the greater good of the whole band
* working with a strong leader who's respected enough by the others to change their method/style etc to achieve this blending.
These aren't advanced techniques. Just basic necessities for playing in a group. Are you suggesting any musician SHOULDN'T play a part that fits? It's their job to play coherent music, yours to (a) assist them in hearing what's going on and (b) deliver it to the audience. It's a completely different job to producing a multitracked recording.
You don't have to write songs. The world doesn't want you to write songs. It would probably prefer it if you didn't. So write songs if you want to. Otherwise, dont. Go fishing instead.
